Nested IF-ELSE Condition in C tutorial

It is perfectly all right if we write an entire if-else construct within either the body of the if statement or the body of an else statement. This is called ‘nesting’of ifs. This is shown in the following program.

/* A quick demo of nested if-else */ main( ) {     int i ;     printf ( "Enter either 1 or 2 " ) ;     scanf ( "%d", &i ) ;     if ( i == 1 )         printf ( "You would go to heaven !" ) ;     else     {         if ( i == 2 )             printf("Hell was created with you in mind");         else             printf("How about mother earth !");     } }
