Short Hand If...Else Statement

There is also a short-hand if else, which is known as the ternary operator because it consists of three operands. It can be used to replace multiple lines of code with a single line.

It is often used to replace simple if else statements:

    
        Syntax :
        variable = (condition) ? expressionTrue : expressionFalse;
    

Instead of writing:

    
        #include<stdio.h>

        int main() {
            int time = 20;
            if (time < 18) {
            printf("Good day.");
            } else {
            printf("Good evening.");
            }
            return 0;
        }
    

    
        #include<stdio.h>

        int main() {
            int time = 20;
            (time < 18) ? printf("Good day.") : printf("Good evening.");
            return 0;
        }
    

It is completely up to you if you want to use the traditional if...else statement or the ternary operator.
