It is always legal in C programming to nest if-else statements, which means you can use one if or else
if statement inside another if or else if statement(s).
Syntax:
The syntax for a nested if statement
is as follows:
if( boolean_expression 1)
{
/* Executes when the
boolean expression 1 is true */
if(boolean_expression
2)
{
/* Executes when the
boolean expression 2 is true */
}
}
You can nest else if...else in the similar way as you have
nested if statement.
Example:
#include
<stdio.h>
int
main ()
{
/* local variable definition */
int a = 100;
int b = 200;
/* check the boolean condition */
if( a == 100 )
{
/* if condition is true then check the
following */
if( b == 200 )
{
/* if condition is true then print
the following */
printf("Value of a is 100 and b
is 200\n" );
}
}
printf("Exact value of a is : %d\n",
a );
printf("Exact value of b is :
%d\n", b );
return 0;
}
When the above code is compiled and executed, it produces
the following result:
Value of a is 100 and b is 200
Exact value of a is : 100
Exact value of b is : 200

Exact value of b is : 200
