C++ Program to Print an Arithmetic Progression.

If the first element of an A.P. is a, and the common difference is d, then the n-th element of that A.P. is a + (n - 1) * d. Write a program to print the first ten digits of an A.P. Obtain a and d from the user.

#include <iostream>
using namespace std;
int main()
    int a, d;
    cout << "Enter a: ";
    cin >> a;
    cout << "Enter d: ";
    cin >> d;
    int counter = 0;
    while (counter++ < 10)
        cout << a + (counter - 1) * d;
        cout << endl;
    return 0;
