Definition:
The conditional operator is also known as "Ternary Operator". The conditional operator contains a condition followed by two statements or values. If the condition is true, the first statement is executed, otherwise the second statement is executed.
Syntax:
CONDITION ? EXPRESSION-1 : EXPRESSION-2;
Example:
a==0 ? printf("A is Zero") : printf("A is Not Zero");
Note:
The additional use of conditional operator is "SELECTIVE ASSIGNMENT".
Programming Example:
#include<stdio.h>
#include<conio.h>
void main()
{
int a,b,max;
clrscr();
printf("Enter Two Number");
scanf("%d%d",&a,&b);
max=a>b?a:b;//Selective Assignment.
printf("Maximum among %d and %d is %d",a,b,max);
}Nesting of Conditional Operator (? :) :
We know that the general form of the conditional operator is condition ? true part : false part. This form can also be interpreted as: If condition then statement else statement.
The nesting of conditional operator generally in two forms.
- Nesting inside false part/else part.
- Condition ? True Part : Condition ? True Part : False Part;
- Nesting inside true part/if part.
- Condition ? Condition ? True Part : False Part : False Part;
