Program to Find the Largest Number using Ternary Operator
  • Difficulty Level : Easy
  • Last Updated : 11 Dec, 2020

The task is to write a program to find the largest number using ternary operator among: 

  • Two Numbers
  • Three Numbers
  • Four Numbers

Examples

Input : 10, 20 
Output : 
Largest number between two numbers (10, 20) is: 20

Input : 25 75 55 15
Output : 
Largest number among four numbers (25, 75, 55, 15) is: 75

A Ternary Operator has the following form,

exp1 ? exp2 : exp3

The expression exp1 will be evaluated always. Execution of exp2 and exp3 depends on the outcome of exp1. If the outcome of exp1 is non zero then exp2 will be evaluated, otherwise, exp3 will be evaluated.

C++




// C++ program to find largest among
// two numbers using ternary operator
#include <iostream>
using namespace std;
 
int main()
{
     
    // Variable declaration
    int n1 = 5, n2 = 10, max;
     
    // Largest among n1 and n2
    max = (n1 > n2) ? n1 : n2;
     
    // Print the largest number
    cout << "Largest number between "
         << n1 << " and " << n2
         << " is " << max << ".";
   
    return 0;
}
