# Mastering C++ Programming: Calculate Summation, Multiplication, and Average of Numbers

## How to write a C++ program to calculate summation, multiplication, and average of numbers?

Can you explain the steps to calculate the summation of the first five numbers, multiplication of the second five numbers, and average of the third five numbers using a C++ program?

## Steps to Calculate Summation, Multiplication, and Average in C++:

In order to calculate the summation, multiplication, and average of numbers in C++, you can follow these steps:

- Read 15 numbers from the user and store them in an array.
- Calculate the summation of the first five numbers by iterating over the first five elements in the array and adding them together.
- Calculate the multiplication of the second five numbers by iterating over the second set of five elements and multiplying them together.
- Calculate the average of the third five numbers by finding their sum and dividing by five.
- Display the results to the user.

## Explanation:

When writing a C++ program to calculate the summation, multiplication, and average of numbers, you need to first read the input numbers and store them in an array. Then, you can use loops to perform the specific calculations on different sets of numbers.

**Summation of First Five Numbers:** To calculate the summation of the first five numbers, you will iterate over the first five elements of the array using a loop and add them together to get the total summation.

**Multiplication of Second Five Numbers:** For the multiplication of the second five numbers, you will iterate over the next set of five elements and multiply them together, storing the result in a variable.

**Average of the Third Five Numbers:** To find the average of the third set of five numbers, iterate over these elements, calculate their sum, and then divide the total by five to get the average.

After performing these calculations, you can display the results to the user, showcasing the summation of the first five numbers, the multiplication of the second five numbers, and the average of the third five numbers.

By following these steps, your C++ program will efficiently handle the task of calculating these metrics and provide accurate results to the user.
