C - Conditional or Ternary operator (?:)



The C conditional or ternary operator returns one of the two values based on the value of boolean expression. It is kind of similar to the if-else statement and helps to write the if-else statements in a short way.

Syntax

//returns value1 if expression is true
//returns value2 if expression is false
expression ? value1 : value2

Return Value

Returns value1 if the expression is evaluated to be true, and value2 if the expression is evaluated to be false.

Example:

In the example below, the ternary operator is used to find out the maximum of two numbers.

#include <stdio.h>

int main (){
  int x = 50;
  int y = 100;

  //maximum of two value
  int max = (x > y) ? x : y;

  //displaying the result
  printf("Maximum value = %d", max);

  return 0;
}

The output of the above code will be:

Maximum value = 100
