NESTING OF IF – ELSE STATEMENT IN C

NESTING OF IF – ELSE STATEMENT IN C WITH EXAMPLE

When a series of decision are involved, we may have to use more than one if else statement in nested form as shown below

Syntax

if(condition 1)
{
if(condition 2)
{
True - Block of Statement 1
}
else
{
false - Block of Statement 2
}
}
else
{
false - Block of Statement 3
}

Note:-

# Condition can be expression or relation.
# If body of statement is only one statement than braces ({}) are not needed.
# Body of the statement may have one or more statement.
# Either true – block of statement or false – block of statement is executed, not both.

Execution:-

When both condition 1 and condition 2 are true than True - Block of Statement 1 is executed.
If condition 1 is true and condition 2 is false than false - Block of Statement 2 is executed.
If condition 1 is false than false – blocked statement 3 is executed.
In each case control is moved to statement that is next to if statement.

Examples:-

Program to solve following problem
The candidate is selected if his age and height is 18 and 5 and more respectively.
