In this article, we will learn how to write a C++ program to find the largest of three numbers. This program is a basic programming exercise that is commonly asked in beginner-level coding interviews. We will explain each step of the code in an easy-to-understand manner.
Before writing the program, we must first understand the problem. We need to find the largest number among three given numbers. Let's assume that we have three variables - A, B, and C - and we want to find the largest number among them.
To solve the problem, we can take the following approach:
Now let's write the code to find the largest of three numbers in C++.
using namespace std;
int A, B, C, temp1, temp2, largest;
cout << "Enter three numbers: ";
cin >> A >> B >> C;
temp1 = (A > B) ? A : B;
temp2 = (temp1 > C) ? temp1 : C;
largest = temp2;
cout << "Largest number is " << largest << endl;
Let's break down the code step-by-step:
Let's say we want to find the largest of the following three numbers: 7, 15, and 3. We will run the above code and input the values.
Enter three numbers: 7 15 3
Largest number is 15
As we can see, the output is 15, which is the largest number among 7, 15, and 3.
In this article, we have learned how to write a C++ program to find the largest of three numbers. We have explained each step of the code in detail and provided an example to help you understand the concept better. By following the approach we have provided, you can easily solve similar problems in the future.
