C++ Program to Generate Multiplication Table

To understand this example, you should know about the following C++ programming topics:

• C++ for Loop

Display Multiplication table up to 10

#include <iostream>
using namespace std;
int main() {
    int n;
    cout << "Enter a positive integer: ";
    cin >> n;
    for (int i = 1; i <= 10; ++i) {
        cout << n << " * " << i << " = " << n * i << endl;
    }

    return 0;
}

Output

Enter an integer: 5
5 * 1 = 5
5 * 2 = 10
5 * 3 = 15
5 * 4 = 20
5 * 5 = 25
5 * 6 = 30
5 * 7 = 35
5 * 8 = 40
5 * 9 = 45
5 * 10 = 50

The program above computes the multiplication table up to 10 only.

The program below is a modification of the above program in which the user is also asked to enter the range up to which the multiplication table should be displayed.

Display multiplication table up to a given range

#include <iostream>
using namespace std;
int main() {
    int n, range;
    cout << "Enter an integer: ";
    cin >> n;
    cout << "Enter range: ";
    cin >> range;

    for (int i = 1; i <= range; ++i) {
        cout << n << " * " << i << " = " << n * i << endl;
    }

    return 0;
}

Output

Enter an integer: 8
Enter range: 12
8 * 1 = 8
8 * 2 = 16
8 * 3 = 24
8 * 4 = 32
8 * 5 = 40
8 * 6 = 48
8 * 7 = 56
8 * 8 = 64
8 * 9 = 72
8 * 10 = 80
8 * 11 = 88
8 * 12 = 96
