C Nested if-else Statements

Nested "if else statements" play an essential role in C programming; It simply means the use of conditional statements inside another conditional statement.

The basic format of the Nested if-else statement is:

Syntax:

if(test_expression one)
{
    if(test_expression two) {
    //Statement block Executes when the boolean test expression two is true.
    }
}
else
{
//else statement block
}

Example of a C Program to Demonstrate Nested if-else Statement

Example:

#include<stdio.h>

void main()
{
    int x=20,y=30;

    if(x==20)
    {
        if(y==30)
        {
            printf("value of x is 20, and value of y is 30.");
        }
    }
}

Execution of the above code produces the following result.

Output:

value of x is 20, and value of y is 30.
