Conditional Operator

Conditional Operator

      The conditional operator is also used for making two-way decisions. It can be used in place of simple 'if-else' structure. It is denoted by ? and : signs. Three operands are used with conditional operator. It is also called ternary operator.      The general syntax of conditional operator is as follows:
                    (condition)   ?  exp1  :  exp2

Write a program that inputs two numbers and displays greater number using conditional operator.

Example in C

#include < stdio.h >

#include < conio.h >

void main ( )

{

      int a , b ;

      clrscr ( ) ;

      printf ( " Enter first Number : " ) ;

      scanf ( " %d " , &a ) ;

      printf ( " Enter second Number : " ) ;

      scanf ( " %d " , &b ) ;

     ( a > b ) ? printf ( " %d is greater " , a ) : printf ( " %d is greater " , b ) ;

      getch ( ) ;

}

Example in C++

#include < iostream >

using namespace std;

int main ( )

{

      int a , b ;

      cout << " Enter first Number " ;

      scanf >> a ;

      cout << " Enter second Number " ;

      scanf >> b ;

     ( a > b ) ? cout << a << " is greater " : cout << b << " is greater " ;

      retirn 0 ;

}

Output of the program Enter first Number: 5 Enter second Number: 15 15 is greater
