C programming

Syntax:

if (condition1) {
// code block for condition1
if (condition2) {
// code block for condition2 inside condition1
} else {
// code block for else inside condition1
}
} else {
// code block for else outside condition1
}

Explanation:

Including numerous if-else statements inside an if and else statement is called nesting. The second if and else statements are said to be nested inside the first if and else statement.

When we enter the if block, the else block is ignored and if we enter the else block, the if block is ignored. Nested if else follow the same working.

C language allows nesting of if-else statements to facilitate better decision making.

Sample code:

         
          #include <stdio.h>
          int main() {
              int x = 10;
              int y = 20;
              if (x == 10) {
                  if (y == 20) {
                      printf("x is 10 and y is 20\n");
                  }
              }
              return 0;
          }

Output:

          x is 10 and y is 20
