Exercise:

Write a C++ program to create multiplication table.

Method 1: Compile a program to create multiplication tables for numbers up till 10.

#include <iostream>
using namespace std;
int main()
{
    int num;
    cout << "Please insert a positive number: ";
    cin >> num;
    cout << "Table of " << num << " up to 10:" << endl;
    for (int i = 1; i <= 10; ++i)
    {
        cout << num << " x " << i << " = " << num * i << endl;
    }
    return 0;
}

Please insert a positive number: 12
Table of 12 up to 10:
12 x 1 = 12
12 x 2 = 24
12 x 3 = 36
12 x 4 = 48
12 x 5 = 60
12 x 6 = 72
12 x 7 = 84
12 x 8 = 96
12 x 9 = 108
12 x 10 = 120

  • The user is asked to enter a number Please insert a positive number: .
  • The compiler runs the number through a for loop and displays the table of the number num entered by the user.
  • 1 integer i is declared equal to 1 before the for loop begins. It checks for the condition if the value of i is smaller than 10, it enters the loop and multiplies num by i.
  • The value of i is incremented by 1 every time the number re-enters the loop.
  • The output is displayed on the screen.

Method 2: Compile a program to create multiplication tables up to a range entered by the user:

#include <iostream>
using namespace std;
int main()
{
    int num, ran;
    cout << "Please insert a positive number: ";
    cin >> num;
    cout << "Please specify your range: ";
    cin >> ran;
    cout << "table of "<< num << " up to " << ran << " is:"<<endl;
    for (int i = 1; i <= ran; ++i)
    cout << num << " * " << i << " = " << num * i << endl;
    return 0;
}

Please Insert a positive number: 9
Please specify your range: 14
table of 9 up to 14 is:
9 * 1 = 9
9 * 2 = 18
9 * 3 = 27
9 * 4 = 36
9 * 5 = 45
9 * 6 = 54
9 * 7 = 63
9 * 8 = 72
9 * 9 = 81
9 * 10 = 90
9 * 11 = 99
9 * 12 = 108
9 * 13 = 117
9 * 14 = 126

  • For method 2, the user is requested to enter the num and the range ran up to which the user wishes to see the table.
  • This method is very similar to method 1, except that the condition to enter the for loop has been changed.
  • The limit to enter the loop was changed from a restricted 10 to the number provided by the user.
  • The output is displayed on the screen.
