C easy program not working - “if”

Question

I tried to write an easy program that compares 3 numbers and prints the biggest of them but it keeps printing all 3 of them and I don\'t get why. That\'s my code:

Answer 1

You have a semicolon after your if condition:

if((x > y) && (x > z));

The semicolon takes the place of the block or statement to be executed when the condition is true. It's as if you had written:

if((x > y) && (x > z))
  {
    ;
  }
  {
    printf("%d",x);
  }

You can hopefully see how this will execute the print statement unconditionally.
