Prerequisite – Operators in C
The conditional operator in C is a ternary operator that is used to evaluate a boolean expression and return one of two values depending on whether the expression is true or false.
Syntax:
The syntax of the conditional operator is as follows:
condition ? value_if_true : value_if_false;
Here, condition is a boolean expression that is evaluated. If the condition is true, then the value of value_if_true is returned, otherwise the value of value_if_false is returned.
Example:
Here’s an example code that demonstrates the use of the conditional operator in C:
#include <stdio.h>
int main() {
int a = 10, b = 5, c;
c = (a > b) ? a : b;
printf("The larger number is: %d\n", c);
return 0;
}
In this example, we declare three integer variables a, b, and c. We then use the conditional operator to assign the larger of the two numbers a and b to c. The boolean expression a > b is evaluated, and if it is true, the value of a is returned, otherwise the value of b is returned. The result is then assigned to c, which is printed to the console.
The output of this program will be:
The larger number is: 10
As you can see, the value of c is assigned the value of a (10), since a is greater than b (5).
