Ternary Operator in C

Ternary Operator in C

If any operator is used on three operands or variable is known as Ternary Operator. It can be represented with ? : . It is also called as conditional operator

The ternary operator is an operator that takes three arguments. The first argument is a comparison argument, the second is the result upon a true comparison, and the third is the result upon a false comparison. Ternary operator is shortened way of writing an if-else statement.

Ternary operator is a?b:c it say that the condition a is true b will be executed else c will be executed.

Advantage of Ternary Operator

Using ?: reduce the number of line codes and improve the performance of application.

expression-1 ? expression-2 : expression-3

In the above symbol expression-1 is condition and expression-2 and expression-3 will be either value or variable or statement or any mathematical expression. If condition will be true expression-2 will be execute otherwise expression-3 will be executed.

a<b ? printf("a is less") : printf("a is greater");

Flow Diagram

Find largest number among 3 numbers using ternary operator

#include<stdio.h>
#include<conio.h>

void main()
{
int a, b, c, large;
clrscr();
printf("Enter any three number: ");
scanf("%d%d%d",&a,&b,&c);
large=a>b ? (a>c?a:c) : (b>c?b:c);
printf("Largest Number is: %d",large);
getch();
}

Enter any three number: 5 7 2
Largest number is 7

#include<stdio.h>
int main()
{
int a=2,b=4,c=9;
int lar;
lar=(((a>b)&&(a>c))?a:((b>c)?b:c));
printf(“Largest Number is: %d”,lar);
return 0;
}

Largest Number is: 9
