Iterative structures, also known as loops, repeat sections of code and are used for tasks like calculating multiple values, computing iterative results, printing tables of data, and processing large amounts of input or array data. The three types of loops in C++ are the while loop, do-while loop, and for loop, each with different test conditions to control the loop execution. Loops can also be nested within each other to perform multiple iterations or to loop through multi-dimensional data structures.

Dynamics Behaviour of Multi Storeys Framed Structures by of Iterative Method AM Publications
Dynamics refers to the branch of mechanics that deals with the movement of objects and the forces that drive that movement. Structural analysis which covers the behaviour of structures subjected to dynamic (actions having high acceleration) loading. Dynamic loads include people, wind, waves, traffic, earthquakes, and blasts. Any structure can be subjected to dynamic loading. Dynamic analysis can be used to find dynamic displacements, time history, and the frequency content of the load. One analysis technique for calculating the linear response of structures to dynamic loading is a modal analysis. In modal analysis, we decompose the response of the structure into several vibration modes. A mode is defined by its frequency and shape. Structural engineers call the mode with the shortest frequency (the longest period) the fundamental mode. This paper presents a study on mode shape, inertia force, spring force and deflection of multi storied framed structures by comparison of stodola’s and Holzer method. This study involves in examination of theoretical investigations of multi storied framed structures. Overall four storey multi storied framed structures and two methods were analysed & comparison of all the mode shape, inertia force, spring force and deflection at the critical cross-section with same configuration loading by keeping all other parameters constant. The theoretical data are calculated using code IS 1893, IS 4326, IS 13920. The all storey mass and stiffens are analysed under the cantilever condition. The research project aims to provide which method is most accuracy to find the mode shape, spring force deflection and inertia force. The studies reveal that the theoretical investigations Stodola’s method is most accuracy compare to the Holzer method. The maximum mode shape, spring force, spring deflection and inertia force is 87.29%, 80 %, 89% and 72% is higher the Stodola’s method compare than Holzer method in same configuration.

Iterative control structures, looping, types of loops, loop workingNeeru Mittal
Introduction to looping, for loop. while loop, do loop jump statements, entry controlled vs exit controlled loop, algorithm and flowchart of loops, factorial of a number
In this chapter we will examine the loop programming constructs through which we can execute a code snippet repeatedly. We will discuss how to implement conditional repetitions (while and do-while loops) and how to work with for-loops. We will give examples of different possibilities to define loops, how to construct them and some of their key usages. Finally, we will discuss the foreach-loop construct and how we can use multiple loops placed inside each other (nested loops).
Java is a computer programming language that is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible.
Python programming language provides the following types of loops to handle looping requirements:
1. While
2. Do While
3. For loop
Python provides three ways for executing the loops. While all the ways provide similar basic functionality, they differ in their syntax and condition-checking time.
C for Loop
Loops are used in programming to execute a block of code repeatedly until a specified condition is met. In this tutorial, you will learn to create for loop in C programming.
C programming has three types of loops:
for loop
while loop
do...while loop
what are loop in general
what is loop in c language
uses of loop in c language
types of loop in c language
program of loop in c language
syantax of loop in c language
In this lecture we will discuss about another flow control method – Loop control.
A loop control is used to execute a set of commands repeatedly
The set of commands is called the body of the loop
MATLAB has two loop control techniques
Counted loops - executes commands a specified number of times
Conditional loops - executes commands as long as a specified expression is true
In computer programming, a loop is a sequence of instruction s that is continually repeated until a certain condition is reached. Typically, a certain process is done, such as getting an item of data and changing it, and then some condition is checked such as whether a counter has reached a prescribed number.

Iteration
1. Chapter 6 – Iteration
Iterative structures, or looping structures, are used in programming to
repeat sections of code. Examples where iteration is important:
• Calculating f(x) for 100 values of x
• Computing a result iteratively until a certain accuracy is reached, such
as in evaluating a series like sin(x) = x – x3/3! + x5/5! – x7/7! + ….
• Printing a table of results
• Allowing the user to correct input values or to rerun a program
• Reading large quantities of data from a data file
• Working with arrays
• Etc
There are three basic types of control structures:
• Sequential structures (or straight-line structures)
• Decision structures (or selection structures or branching structures)
• Iterative structures (or looping structures)
These structures are illustrated on the following page: 1

(straight-line structure) (decision or branching structure) (looping structure)
3. Iterative Structures in C++
There are three types of iterative structures in C++:
• while loop
– Continue looping while a condition is true
– Pre-test on the condition, so loop is executed 0 or more times
• do-while loop
– Continue looping while a condition is true
– Post-test on the condition, so loop is executed 1 or more times
• for loop
– Loop for a specific number of iterations based on an index variable
4. while loop
Key features:
• A pre-test is used at the beginning of the loop
• The loop is executed 0 or more times (until the condition is false)
• The test condition must be initialized before the loop
Form: Example 1: while loop
while (condition) int i = 1;
{ while (i <= 5)
statement(s) {
} cout << “Loop #” << i << endl;
i++;
Note: braces optional }
if only one statement.
6. Example 3: while loop
Write a C++ program to calculate the average of an unknown number of
grades as follows:
• Prompt the user to enter a grade each time through the loop
• Update the sum and number of grades
• Prompt the user to enter a negative grade after the last valid grade
• Continue looping while the input grade is not negative
7. Example 4: while loop
Write a C++ program to evaluate e (the base of the natural log) to 5
digits after the decimal point using the following series:
e = 1/0! + 1/1! + 1/2! + 1/3! + …..
Display the final value of e (it should be 2.71828).
8. do while loop
Key features:
• A post-test is used at the end of the loop
• The loop is executed 1 or more times (until the condition is false)
• The loop must be executed at least once!
• It is not necessary to initialize a test condition before the loop
• Unlike the while loop, there is a semicolon after the condition.
Form:
do
{
statement(s)
}
while (condition);
Note: braces optional
if only one statement.
10. Example 2: do while loop
Write a C++ program to determine the smallest integer N such that
N3 – 2N2 > 100,000
Display the result.
11. for loop
• Often the best loop structure when you know how many times the
instructions in the loop are to be executed.
• The for loop has three parts:
– Initialization expression – a loop control variable is assigned an initial value
– Conditional statement – the loop is repeated as long as this is true
– Step – specifies how to modify the loop variable after each pass thru the loop
• Form:
for (initialization expression; conditional statement; step)
{
statement(s)
}
Note: braces optional if only one statement.
For loop – Example 1:
for (i = 1; i <= 10; i++)
{ Result: “Hello!” is
cout << “Hello!” << endl; displayed ten times.
}
12. for loop – Example 2
Display sin(α) for α = 0 to 90° to 10° steps.
13. for loop – Example 3 20
Display the result of the following summation: Sum = ∑ n 3
n =1
14. for loop – Example 4
Determine the output in each case below:
LoopCount = _______
LoopCount = _______
LoopCount = _______
LoopCount = _______
LoopCount = _______
15. for loop – Example 5
Find the average of 100 grades in a data file.
16. Nested for loops
There are many cases where it is useful to form nested loops, or loops
inside or other loops. An example is illustrated below:
for (int i = 1; i < = 4; i++)
{
statement(s)
for (int j = 1; j <= 3; j++)
Outer loop
{ Inner loop
statement(s)
}
statement(s)
}
17. Tracing through nested for loops
It is often necessary to trace through a nested loop structure to
determine the resulting calculations, displayed values, etc. Using a
table can be helpful.
Example: Trace through the nested loop shown below:
for (int i = 1; i < = 4; i++) i j k
{
for (int j = 1; j <= 3; j++)
{
k = i + j;
}
}
18. Nested for loops – Example 1
Determine the output for each part below.
int Count = 0;
for (int i = 1; i < = 5; i++)
for (int j = 1; j <= 4; j++) Count = __________
for (int k = 1; k <= 3; k++)
Count++;
cout << “Count = “ << Count;
int Count1 = 0, Count2 = 0, Count3 = 0;
for (int i = 10; i > = 0; i-=2)
{
Count1++;
for (int j = 3; j <= 24; j+=3) Count1 = __________
{
Count2++;
for (int k = -20; k <= 20; k+=5) Count2 = __________
Count3++;
}
} Count3 = __________
cout << “Count1 = “ << Count1 << endl;
cout << “Count1 = “ << Count1 << endl;
cout << “Count1 = “ << Count1 << endl;
19. Nested for loops – Example 2
Determine the output for the instructions shown below.
for (int i = 1; i < = 2; i++)
for (int j = i; j <= 3; j++)
for (int k = j; k <= 4; k++)
cout << i << j << k << endl;
Output:
20. Nested for loops – Example 3
Data file datex3.in contains 100 numbers with 10 numbers in each
row. Determine the sum of the values in each row.
21. Infinite loops (forever loops)
It is sometimes useful to construct a loop which will execute forever.
Such loops are sometimes called infinite loops or forever loops.
Examples:
• Monitor an alarm system 24 hours per day and sound an alarm when
appropriate
• Run the display on a gas pump and display advertising until a user
presses a button to indicate that they want to pump gas.
Notes:
• An infinite loop may be exited at any point using a break statement.
• You can generally stop an infinite loop from the keyboard by
pressing Ctrl+C.
22. Infinite loops (forever loops) – form
Infinite loops can be created easily using any of the three types of
loop structures introduced:
Infinite while loop: while (1)
{
statement(s)
}
Infinite do while loop:
do
{
statement(s)
}
while (1);
Infinite for loop: for(;;)
{
statement(s)
}
23. Infinite loops - examples //clock program
while (1)
{
statements to display time
}
// alarm program
do
{
statements to sound alarm if certain inputs occur
}
while (1);
// vending machine
for(;;)
{
statements to wait for inputs
statements to release product
statements to dispense change
}
24. Structures with an indeterminate number of loops
For loops with an indeterminate number of iterations, we can use:
– Do while loop – exit at the top of the loop
– While loop – exit at the bottom of the loop
– Forever loop – exit in the middle of the loop using a break statement
while (x < 2) do for(;;)
{ { {
statement(s) statement(s) statement(s)
} } if (!(x<2)) break;
while (x < 2); statement(s)
Exit from top of loop
once x<2 is false }
Exit from bottom of
loop once x<2 is false Exit from middle of
loop once x<2 is false
Note: Any number of exit points could be provided in
any of the loop structures above using break statements.
25. Forever loop - Example
Write a C++ program to evaluate e (the base of the natural log) using the
infinite series e = 1/0! + 1/1! + 1/2! + 1/3! + ….. accurate to 8 digits
after the decimal point using a forever loop with a break statement.
26. Graphing in C++
Generating graphs in C++ is a fairly advanced topic. However, it is easy
to write a C++ program to send the x,y data to a data file where it can
then be graphed using other programs like Excel or MatLab.
Excel can easily open data files where columns of numbers are separated
by commas, spaces, or tabs. If they are separated by commas, the file is
sometimes called a “commas delimited file.”
Commas delimited
data file A:xydata.dat
C++ Program Excel
… 10,125 y
Ofstream OutData(“A:xydata.dat”) 12,137
//calculate x and y values 14,156
… 16,189
OutData << x << “,” << y << endl; 18, 211 x
… …
27. Example: Graphing in C++
Graph the function y = 100e-x for x = 0.0, 0.2, 0.4, … , 5.0
28. Example: Graphing in C++
• Open the data file A:OutToExcel.dat with Excel (select All Files
(*.*) for File Type.
• The Text Import Wizard (Step 1 of 3) should appear as shown below.
The default is a delimited file. Select Next to continue.
• The Text Import Wizard (Step 2 of 3) should appear next. Select
Comma as the delimiter (default is Tab). Select Next to continue.
29. Example: Graphing in C++
• The Text Import Wizard (Step 3 of 3) should appear next. This
screen lets you select data format. The default is General which is
sufficient for this example. Select Finish .
• The data should now appear in columns A and B in Excel. Add the
graph.
