This document summarizes different types of flow control statements in C/C++, including sequential statements, conditional statements, and iterative/looping statements. Conditional statements include if, if-else, nested if-else, and if-else ladder statements. Examples are provided for each type of conditional statement. Pseudocode is given for programs to find the greatest of two numbers using if, enter and output uppercase and lowercase characters, find the greatest of three numbers using nested if-else, and calculate tax based on salary ranges using an if-else ladder.

2. Statement is instruction
that execute at run
time
Type of statements
1. Sequential statement
2. Conditional statement
3. iterative/looping
statement
4. Branching statement

3. Sequential
statement
• These are those
statements which
execute starting from
line1 to line 2 and so on.
• Till now the programs
we have done are
example of sequential
statements as
lines/statements in
programs are executed
in the sequence as

4. Conditional
statement
• Are those statements which will depend
on condition for their execution.
Types of Conditional Statements
• If condition
• if-else condition
• Nested if-else
• If-else ladder

5. if
condition
if(condition)
{
statement1
;
statement2
;
..........
}
Stament1 and statement2 are conditional

6. WAP to find greatest of 2
numbers using if
condition
• lvalue : An expression that is an
lvalue may appear as either the left-
hand or right-hand side of an
assignment.

9. if-else
condition
• if evaluates to true. It does nothing
when the expression evaluates to
false.
• Else is used when we want some
statements to be executed when if
evaluates to be false. So if the
condition is true, if is executed else
, else is executed.

10. If(condition)
{
Statement
1;
Statement
2;
}
else
{
Statement
3;

• WAP to enter Small Case Character
And Output Upper Case Character
and When input character is Upper
case, Output small case character

15. Nested if-
else
• if-else construct within either the body
of the if statement or the body of an
else statement or both. This is called
nesting‘of ifs.

• WAP to find greatest of 3 numbers
using nested if-else

18. If-else
Ladder
• It is used to check multiple
conditions.
• Every else is associated with its
previous if.
• The last else goes to work only if all
the conditions fail.
• Even in else if ladder the last
else is optional.

20. • WAP to calculate tax for entered salary.
If salary > 10000, tax is 2 %. If salary
lies between 5000 and 10000, tax is
1.5 %. If salary is in between 3000 to
5000 , Tax is 1 % and if salary is lesser
then 3000, Tax is 0%
