Nested if-else Statement in C

← Back to Menu

The if-else construct may contain other if or if-else constructs, a feature called nesting. We must be careful in this case, as we have to keep track of the different ifs and the corresponding elses. 
Syntax: 
          if(conditional_expression)
          {
                     if(conditional_conditional_expression-1){
                                statement(s);
                     } else {
                                statement(s);
                     }
           } else {
                      statement(s);
            }

Example: 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

#include<stdio.h> void main(){ int com, math; com = 55; math = 44; if(com>=50){ if(math>=50){ printf("You are selected !!"); } else { printf("You are not selected !!"); } } else { printf("Sorry !! you are not selected !!"); } getch(); }

Output

You are not selected !!
