If/Else

if/else Example

Example if/else, if.c:

#include <stdio.h>

main() {

     int number;

     printf ("Enter a magical number: ");

     scanf ("%d", &number);

     if (number >= 100) {

          printf ("Your number is very magical! \n");

     } else {

          printf ("Your number needs more magic :( \n"); 

     }

} 

Things to note:

• there's a condition to test whether things are true or false
  • a condition is a boolean expression (or function) that returns true or false
• there's a true block of code
  • these lines of code are executed when the condition is true
• there's a false block of code
  • these lines of code are executed when the condition is false
• if.c is utilizing the if/else control statement
