Video Link: https://youtu.be/05xv2nMj6Ls Tutorial Link: https://www.programiz.com/c-programming

Syntax :

test_condition ? expression1 : expression2;

Example: Ternary Operator

Example 1:

#include <stdio.h>

int main() {

  int age = 15;

  (age >= 18) ? printf("You can vote") : printf("You cannot vote");

  return 0;
}

Output

You cannot vote

Example 2:

#include <stdio.h>

int main() {

  int age = 24;

  (age >= 18) ? printf("You can vote") : printf("You cannot vote");

  return 0;
}

Output

You can vote

Example 3 : Using variable in ternary operator

#include <stdio.h>

int main() {

  char operator = '+';

  int num1 = 8;
  int num2 = 7;

  int result = (operator == '+') ? (num1 + num2) : (num1 - num2);
  printf("%d", result);

  return 0;
}

Output

15

Programming Task

Q. Can you create a program to check whether a number is odd or even? To create this program, create a variable named number and assign a value to it. Then using a ternary operator check if the number variable is odd or even.

• If number is odd, print "The number is Odd"
• If number is even, print "The number is Even"

Solution :

#include <stdio.h>

int main() {
    
    int number;
    printf("Enter a number: ");
    scanf("%d", &number);
    
    (number % 2 == 0) ? printf("It is even ") : printf("It is odd");
    
    return 0;
}

Output

Enter a number: 5
It is odd
