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.
