C++ Find Largest and Smallest among 3 Numbers Program
In this tutorial, we will learn how to Find the Largest and the Smallest among 3 numbers entered by the user, in the C++ programming language.
This program demonstrates the flow of the if-else blocks in the cpp programming language by making use of this example.
using namespace std;
cout << "\n\nWelcome to Studytonight :-)\n\n\n";
cout << " ===== Program to find the Largest and the Smallest number among 3 numbers ===== \n\n";
int n1, n2, n3, smallest, largest;
//taking input from the command line (user) all at once
cout << " Enter the three numbers : \n\n\n";
cin >> n1 >> n2 >> n3;
//assign initial value for comparison (as the undefined variables store a random value)
smallest = n1;
largest = n2;
//logic to find the Smallest and the Largest number - Remember, each variable stores only the latest value inserted into it.
if (n2 < smallest)
smallest = n2;
if (n3 < smallest)
smallest = n3;
if (n3 > largest)
largest = n3;
if (n2 > largest)
largest = n2;
cout << "\n\n The Smallest number among ( " << n1 << ", " << n2 << ", " << n3 << " ) is : " << smallest;
cout << "\n\n The Largest number among ( " << n1 << ", " << n2 << ", " << n3 << " ) is : " << largest;
cout << "\n\n\n";
