Ternary Operator in C Language - Codzify Tutorials
What are Conditional Operators ?
The conditional operators ? and : are sometimes called ternary operators since they take three arguments. In fact, they form a kind of foreshortened if-then-else. It is very easy to understand Ternary Operator in C . Consider the following syntax below for better understanding,
Syntax :-
expression 1 ? expression 2 : expression 3
What this expression says is: "if expression 1 is true (that is, if its value is non-zero), then the value returned will be expression 2, otherwise the value returned will be expression 3"
It's equivalent if statement will look like this
if(expression 1)
{
expression 2;
}
else
{
expression 3;
}
Example :-

#import <stdio.h>
#import <conio.h>
void main( ) {
int a , b;
a = 10;
printf( "Value of b is %d\n", (a == 1) ? 20: 30 );
printf( "Value of b is %d\n", (a == 10) ? 20: 30 );
Output :-
Value of b is 30 Value of b is 20
Short Description of Example :-
(a == 1) ? 20: 30
Firtsly a == 1 is being evaluated but since a=10 condition becomes false so output will be 30.
(a == 10) ? 20: 30
Firtsly a == 10 is being evaluated but since a=10 condition becomes true so output will be 20 :)
It's equivalent if statement will look like this
a = 10;
if(a == 1 )
printf("20"); --Just for understanding
else
printf("30") ;
