C++ Program to find Average of N Numbers

Using for loop

In the following example, we will find the average of numbers between 1 and 10 using for loop.

Example

C++ Compiler
#include <iostream> #include <cmath> using namespace std; int main() { int start = 1; int end = 10; int total = 0; int count = (end - start) + 1; float average = 0; cout << "Average of numbers between " << start << " and " << end << ":\n"; for(start=start; start<=end; start++) total += start; cout << "\nTotal = " << total; cout << "\nCount = " << count; average = (float) total / count; cout << "\nAverage is " << average; return 0; }

Using while loop

In the following example, we will find the average of numbers between 1 and 10 using while loop.

Example

C++ Compiler
#include <iostream> #include <cmath> using namespace std; int main() { int start = 1; int end = 10; int total = 0; int count = (end - start) + 1; float average = 0; cout << "Average of numbers between " << start << " and " << end << ":\n"; while(start <= end) { total += start; start++; } cout << "\nTotal = " << total; cout << "\nCount = " << count; average = (float) total / count; cout << "\nAverage is " << average; return 0; }

Using do while loop

In the following example, we will find the average of numbers between 1 and 10 using do while loop.

Example

C++ Compiler
#include <iostream> #include <cmath> using namespace std; int main() { int start = 1; int end = 10; int total = 0; int count = (end - start) + 1; float average = 0; cout << "Average of numbers between " << start << " and " << end << ":\n"; do{ total += start; start++; }while(start <= end); cout << "\nTotal = " << total; cout << "\nCount = " << count; average = (float) total / count; cout << "\nAverage is " << average; return 0; }

Find Average of N Numbers for any Given Range

In the following example, we will find the average of N numbers between the user given range.

Example

C++ Compiler
#include <iostream> #include <cmath> using namespace std; int main() { int start, end; cout << "Enter a (int) starting number: "; cin >> start; cout << "Enter an (int) ending number: "; cin >> end; int total = 0; int count = (end - start) + 1; float average = 0; cout << "Average of numbers between " << start << " and " << end << ":\n"; for(start=start; start<=end; start++) total += start; cout << "\nTotal = " << total; cout << "\nCount = " << count; average = (float) total / count; cout << "\nAverage is " << average; return 0; }
