Conditional Operator in C

Conditional operator

Q) Give syntax for the conditional operator.
Q)Give syntax for the conditional operator and explain with a flow chart.
Q)Give syntax for the conditional operator and explain with an example.

• The C language has an unusual operator, useful for making a two-way decision. This operator is a combination of? and: and takes three operands. That operator is commonly known as the conditional operator. It is also known as a ternary operator as it has three operators. It has the following general form.
• Conditional-expression ? expression1 : expression2
• Here, conditional expression, expression1 and expression2 are the expressions.

Working of Condition operators:

• Conditional- expression is evaluated first. If it is true (i.e. non-zero), then expression 1 will be evaluated and returned as the result otherwise expression2 will be evaluated and returned as the result. Note that only one of the expressions (either expression 1 or expression 2) is evaluated.

consider the following piece of code:

a=10
b=15:
x=(a>b) ? a:b;

Here, x will contain a value of b (i.e. 15)

• Note: conditional operator,  ternary operator and operator having three operands are the same things.

Q) Write any program to demonstrate the working of the conditional operator.
Q) Write a program to find a larger number from two numbers using a conditional operator.

/* program for finding the largest out of two numbers, using conditional operator */

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

void main()
{
int a, b, 1;
clrscr();
printf("Enter two numbers : ")
scant("%d%d", &a, &b);

1= (a>b) ? a:b;

printf("nLargest number is %d", 1);
getch();
}

Output:
Enter two numbers: 10 12
Largest number is 15
