C++ Program to Generate Multiplication Table

Example 1: Display Multiplication Table up to 10

#include <iostream>
using namespace std;

int main() {

    int n;

    cout << "Enter a positive integer: ";
    cin >> n;

    // run a loop from 1 to 10
    // print the multiplication table
    for (int i = 1; i <= 10; ++i) {
        cout << n << " * " << i << " = " << n * i << endl;
    }
    
    return 0;
}

Output

Enter a positive 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

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

Example 2: Display Multiplication Table up to a Given Range

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

#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
