===== Тернарный оператор =====

''[первый операнд - условие] ? [второй операнд] : [третий операнд]''

читать как: ''если условие ? то : иначе''

<code c>
#include <stdio.h>
 
int main(void){
  int x=5;
  int y=2;
   
  int z = x > y ? x-y : x+y;
     
  printf("z = %d", z);        // z = 3
  return 0;
}
