Conditional Operator in C

The Conditional Operator in C, also called a Ternary operator, is one of the Operators, which used in the decision-making process. The C Programming Conditional Operator returns the statement depends upon the given expression result.

The basic syntax of a Ternary Operator in C Programming is as shown below:

Test_expression ? statement1: statement2

From the above syntax, If the given test condition is true, then it returns statement1, and if it is false, statement2 will return.

Conditional Operator in C Example

In this program, we use the Conditional Operator to find whether the person is eligible to vote or not.

/* Ternary Operator in C Example */

#include<stdio.h> 

int main()
{
  int age;

  printf(" Please Enter your age here: \n ");
  scanf(" %d ", &age);

 (age >= 18) ? printf(" You are eligible to Vote ") :
               printf(" You are not eligible to Vote ");

 return 0;
}

ANALYSIS

This Ternary Operator in c program allows the user to enter his or her age and assign the user entered integer value to age variable. If the user entered value is 18 or above, it will print the first statement after the ? symbol.

printf(" You are eligible to Vote ")

If the user enters below 18, the second statement (which is after the : symbol) will print.

printf(" You are not eligible to Vote ")

OUTPUT

Let us try with a different value to test the conditional operator.
