?: Operator

The conditional operator in C is kind of similar to the if-else statement as it follows the same algorithm as of if-else statement but the conditional operator takes less space and helps to write the if-else statements in the shortest way possible. It is also known as the ternary operator in C as it operates on three operands.

Syntax of Conditional/Ternary Operator in C :

The conditional operator can be in the form
variable = Expression1 ? Expression2 : Expression3;

Or the syntax can also be in this form

variable = (condition) ? Expression2 : Expression3;

Or syntax can also be in this form

(condition) ? (variable = Expression2) : (variable = Expression3);

Working of Conditional/Ternary Operator in C

The working of the conditional operator in C is as follows:
• Step 1: Expression1 is the condition to be evaluated.
• Step 2A: If the condition(Expression1) is True then Expression2 will be executed.
• Step 2B: If the condition(Expression1) is false then Expression3 will be executed.
• Step 3: Results will be returned.

Sample code:

output:

 y = (x  > 6 ? 4 : 6);
