34. Ex. No: 11 STRING MANIPULATION
AIM:
To write a C program to perform string manipulation function like string concatenation, comparison,
find the length and string copy without using library functions.
ALGORITHM:
Step 1: Start
Step 2: Declare character array string1[n], string2[n], string3[n]
Step 3: Set a infinite loop and Create a menu driven to perform string manipulation function
Step 4: Enter a choice and Perform string copy, string compare, string concatenation and string length
Step 5: Print the result
Step 8: Stop
DESCRIPTION:
The program string manipulation includes all the string operations like
a) String copy: The string copy use to one string to another. It assigns the contents of each character from
string2 to string1 until null character occurrence and place null character ‘0’ at the end of destination
string1. For example,
Read the string1: lotus
The copied string is lotus
b) String compare: The string comparison compares string1 and string2 for their equality, if both are equal
then print “The strings are equal” or print “The strings are not equal”. Here each array character from one
string can be checked for equality with another string until null character ‘0’ is read. For example,
Read the string1: piece
Read the string2: peace
The given two strings are not equal
c) String concatenation: The string concatenation forms string1 and string2 together. The concatenation
string can be obtained by adding each character from the string1 into string3 after finished this then add
string2 each character into string3 and place null character ‘0’ at the end of the string3. For example,
Read the string1: good
Read the string2: day
The concatenated string is good day
d) String length: The string length counts the number of character presented in the string arrays until null
character is read. For example,
Read a string1: rose
The length of rose is 4

35. Ex. No: 12 SORTING ALPHABETICAL ORDER
AIM:
To write a C program to arrange names in alphabetical order.
ALGORITHM:
Step 1: Start
Step 2: Declare character array name[n][m] and temp[n]
Step 3: Read n number alphabet to sort and Initialize name[n]
Step 4: Set a nested loop variable i=1 and j=i+1 to iterate
Step 5: Compare element and do swapping,
Step 5.1: temp=name[i]
Step 5.2: name[i]=name[j]
Step 5.3: name[j]=temp
Step 6: Print the sorted array name[n]
Step 7: Stop
DESCRIPTION:
Arranging the names in the ascending/descending order using string sorting. Each string is read using a
scanf() function with %s format. The alphabet of each name is checked according to the alphabetical order. The order
is checked by comparing each name by strcmp() function and if it gives greater than zero comparison result then we
use strcpy() function to swap variable with another variable. Print the sorted list of name. For example,
Read unsorted array of items:
London Delhi Chennai Paris Bombay
Print sorted alphabetical List:
Bombay Chennai Delhi London Paris

36. Ex. No: 13 MATRIX MULTIPLICATION
AIM:
To write a ‘C’ program to perform matrix multiplication.
ALGORITHM:
Step 1: Start
Step 2: Declare two dimensional array for the matrix A, matrix B and matrix C
Step 3: Read the size and elements for the row and column of the A matrix and B
matrix
Step 4: Set a nested for loop to iterate and calculate C[i][j]=C[i][j]+A[i][k]*B[k][j]
i.e., row size of first matrix A and columns size of matrix B
Step 5: Print the elements of the matrix A and matrix B in matrix form
Step 6: Print the resultant matrix C
Step 7: Stop
DESCRIPTION:
This is the most often used and most important way to multiply matrices. It is defined between two matrices
only if the number of columns of the first matrix is the same as the number of rows of the second matrix.
Formally, for
,
then
where the elements of A.B are given by
for each pair i and j with 1 ≤ i ≤ m and 1 ≤ j ≤ p. The algebraic system of "matrix units" summarizes the abstract
properties of this kind of multiplication.

37. For example:
Therefore the product C of two matrices A and B is defined as
Cik = Aij Bjk
Where ‘j’ is summed over for all possible values of ‘i’ and ‘k’ and the notation above uses Einstein
summation convention. The implied summation over repeated indices without the presence of an explicit sum sign is
called Einstein summation, and is commonly used in both matrix and tensor analysis. Therefore, in order for matrix
multiplication to be defined, the dimensions of the matrices must satisfy.
(n*m) (m*p) = (n*p)
Where (a*b) denotes a matrix with ‘a’ rows and ‘b’ columns

38. Ex. No: 14 FACTORIAL AND FIBONACCI SERIES
AIM:
To write a ‘C’ program to find the Factorial and Fibonacci of a given numbers using recursive function.
ALGORITHM 1:
Step 1: Start
Step 2: Read the number ‘n’
Step 3: Create and Call function fact (n) repetitively by itself
Step 3.1: Check if n==1, return (1)
Step 3.2: else return (n*fact (n-1))
Step 4: Print the factorial of the number

ALGORITHM 2:
Step 1: Start
Step 2: Read the number ‘n’
Step 3: Create and Call function fib (n) repetitively by itself
Step 3.1: Check if n=2, initialize a=0, b=1
Step 3.2: else fib (n-1), swap the variables c=b, b=a+b, a=c
Step 4: Print the Fibonacci sequence
Step 5: Stop
DESCRIPTION:
a) Factorial
The Factorial of an integer n is the product of consecutive integers from 1 to n is performed by using
recursive function, where a function calls itself. That is,
Factorial n= n! = n x (n-1) x ……. x 1
The Factorial of a number is the product of all the whole numbers, except zero, that are less than or equal to
that number. For example, to find the factorial of 5, multiply together all the whole numbers, except zero, that are less
than or equal to 5. i.e,
5 x 4 x 3 x 2 x 1 = 120
b) Fibonacci
The Fibonacci of an integer n is the sum of the two preceding numbers in the series, is performed by using
recursive function, where a function calls itself. That is, Fibonacci series is formed by starting with 0 and 1 and then
adding the later two numbers to get the next. For example,
To print the number in the sequence 0 1 1 2 3 5 8 13 21 ……….

Step 4: Print the element position found or not in the array arr[n]
Step 5: Stop
ALGORITHM 2:
Step 1: Start
Step 2: Read the size and number into array arr[n]
Step 3: Create and call function bin(arr[n],n)
Step 3.1: Set a while loop and evaluate (first<=1)
Step 3.2: Calculate middle=(first+last)/2
Step 3.3: Check if(key<arr[middle])calculate last=middle-1
Step 3.4: Else if(key>arr[middle])calculate first = middle +1
Step 4: Print the element position found or not in the array arr[n]
Step 5: Stop
DESCRIPTION:
a) Sequential Search
Linear search, also known as sequential search, means starting at the beginning of the data and
checking each item in turn until either the desired item is found or the end of the data is reached. This is the
simplest known technique for searching an array for a particular data element and scans the element one by
one until the end of array. If search is successful then it will return the location of element, otherwise it will
return the element not found. For example, Find the key element 3 in the array arr[9].

40. Iteration 1:
index variable i=0
0 1 2 3 4 5 6 7 8
arr
10 15 8 3 25 50 33 21 39
Key element(k) = Is (3=10) false
Iteration 2:
i=1
0 1 2 3 4 5 6 7 8
arr
10 15 8 3 25 50 33 21 39
Key element(k) = Is (3=15) false
Iteration 3:
i=2
0 1 2 3 4 5 6 7 8
arr
10 15 8 3 25 50 33 21 39
Key element(k) = Is (3=8) false
Iteration 4:
i=3
0 1 2 3 4 5 6 7 8
arr
10 15 8 3 25 50 33 21 39
Key element(k) = Is (3=3) True
Now we find the index of the element in array and through index we can access information easily.

41. b) Binary Search
The binary search is the simpler and faster than the linear search. Binary search is called so became
on each search the array to be searched is divided into parts, one of which is ignored as it will not contain
the required element.
The condition for binary search is that all the data should be in sorted array. We compare the
element with middle element of the array. If it is less than the middle element then we search it in the left
portion of the array and if it is greater than the middle element then search will be in the right portion of the
array. Now we will take that portion only for search and compare with middle element of that portion. This
process will be in iteration until we find element or middle element has no left or right portion to search. For
example, Find the key element 49 in the array arr[10].
Iteration 1:
First=0 Middle=(0+9)/2=4 Last=9
0 1 2 3 4 5 6 7 8 9
arr
10 18 19 20 25 30 49 57 64 72
Iteration 2:
First=5 Middle=(5+9)/2=7 Last=9
0 1 2 3 4 5 6 7 8 9
arr
10 18 19 20 25 30 49 57 64 72
Iteration 3:
First=5 Last=9
0 1 2 3 4 5 6 7 8 9
arr
10 18 19 20 25 30 49 57 64 72
Middle=(5+7)/2=6
Key element
Now we find the index of the element in array and through index we can access information easily.

DESCRIPTION:
Structure is the collection of dissimilar data items stored under a common name, where we can declare and
store different data types on one name. In the same way define array of structure, in such type every element is of
structure type.
The student mark statement program requires the student’s details along with marks of each subject. Then
compare each subject marks to find out whether the subject got greater than or equal to 35 marks. If not then print the
student is “Fail”, otherwise calculate total and average marks of the student. Then find out the student grade whether
the student got Distinction, First, Second and Third Class by comparing the average marks of the student in different
criteria’s as per the given below tabular to get the student grade and finally print all the details of the student mark
statement list in a format.
