Program to check the largest number among three numbers

In this example, We will learn how to check the largest number among three numbers using the C++ programming language.

To understand this example, You must have the knowledge of

• IF Else Conditional Statement

In this example, We we will ask for three numbers and compare each numbers to get largest number. Let’s look an example to make clear concepts:

#include <iostream>
using namespace std;

int main() {    
    float n1, n2, n3;

    cout << "Enter three numbers: ";
    cin >> n1 >> n2 >> n3;

    if(n1 >= n2 && n1 >= n3)
        cout << "Largest number: " << n1;

    else if(n2 >= n1 && n2 >= n3)
        cout << "Largest number: " << n2;
    
    else
        cout << "Largest number: " << n3;
  
    return 0;
}

The output of above program is

Enter three numbers : 5, 7, 9
Largest Number: 9
