C++ program to print the multiplication table of a number

In this article, you will learn and get code to print a multiplication table of numbers using a C++ program. Here is the list of programs for printing the multiplication table:

Multiplication Table for 2
Print the multiplication table for any given number
Print the multiplication table from 1 to 10
Print a multiplication table of all the numbers in a given range

What is a multiplication table?

A multiplication table shows a list of multiples of a particular number, from 1 to 10. For instance, the multiplication table for 3 is:

3 * 1 = 3
3 * 2 = 6
3 * 3 = 9
3 * 4 = 12
3 * 5 = 15
3 * 6 = 18
3 * 7 = 21
3 * 8 = 24
3 * 9 = 27
3 * 10 = 30

Note: Typically, the list of multiples is from 1 to 12. But in this article, we've created all the programs for printing the multiplication table based on multiples from 1 to 10 only.

Print Multiplication Table of 2 in C++

Let's start with the very first program in this article, which prints the multiplication table of 2:

#include<iostream>
using namespace std;
int main()
{
    int num=2, i, res;
    for(i=1; i<=10; i++)
    {
        res = num*i;
        cout<<num<<" * "<<i<<" = "<<res;
        cout<<endl;
    }
    cout<<endl;
    return 0;
}

This program was built and runs under the Code::Blocks IDE. Here is its sample output:

The dry run of this program goes like this:

Initially, num = 2
Now the execution of the for loop begins. Its initialization (first statement) gets executed at first, but only once.
So 1 gets initialized to i, and the condition i<=10 or 1<=10 evaluates to be true. Therefore, program flow goes inside the loop.
And then num*i or 2*1 or 2 is set to res.
Now, using the following statement:
cout<<num<<" * "<<i<<" = "<<res;
2 * 1 = 2, gets printed on the output.
The third statement:
cout<<endl;
gets executed, which prints a newline.
Now the program flow goes to the update (third statement) of the for loop and increments the value of i. So i=2
The condition i<=10 or 2<=10 again evaluates to be true, therefore the program flow again goes inside the loop.
This process continues until its condition is evaluated as false.
In this way, the multiplication table of 2 gets printed on the output screen.

In C++, print a multiplication table for any given number

To print a table of any given number in C++ programming, you have to ask the user to enter the number. Then start multiplying that number from 1 to 10, one by one, and display the multiplication result at the time of multiplying, as shown here in the following program.

#include<iostream>
using namespace std;
int main()
{
    int num, i, res;
    cout<<"Enter the Number: ";
    cin>>num;
    for(i=1; i<=10; i++)
    {
        res = num*i;
        cout<<num<<" * "<<i<<" = "<<res;
        cout<<endl;
    }
    cout<<endl;
    return 0;
}

Here is the initial output produced by this C++ program:

Now supply the input, say 5, and press the ENTER key to print its table as shown in the snapshot given below:

Print the multiplication table from 1 to 10 in C++

This program prints tables from 1 to 10. That is, first table 1 gets printed, then table 2 gets printed, and so on up to table 10:

#include<iostream>
using namespace std;
int main()
{
    int num, i, j, res;
    cout<<"-----------Table from 1 to 10--------\n\n";
    for(i=1; i<=10; i++)
    {
        num = i;
        cout<<"Table of "<<num<<": ";
        for(j=1; j<=10; j++)
        {
            res = num*j;
            cout<<res<<"  ";
        }
        cout<<endl;
    }
    cout<<endl;
    return 0;
}

Here is the sample output produced by this program:

In C++, print a Multiplication Table within a Specific Range

This program allows the user to enter a range and print a table with all of the numbers in that range. For example, if the user enters a range of 3 and 15, then a table of all numbers from 3 to 15 gets printed.

#include<iostream>
using namespace std;
int main()
{
    int numOne, numTwo, num, i, j, res;
    cout<<"Enter the Range: ";
    cin>>numOne>>numTwo;
    cout<<"--------Table from "<<numOne<<" to "<<numTwo<<"--------\n\n";
    for(i=numOne; i<=numTwo; i++)
    {
        num = i;
        cout<<"Table of "<<num<<": ";
        for(j=1; j<=10; j++)
        {
            res = num*j;
            cout<<res<<"  ";
        }
        cout<<endl;
    }
    cout<<endl;
    return 0;
}

Here's an example run with user input: 3 for the first number and 15 for the second:

What if the user enters two numbers in such a way that the first number is greater than the second?
To solve this problem, use this program instead of the previous one:

#include<iostream>
using namespace std;
int main()
{
    int numOne, numTwo, num, i, j, res;
    cout<<"Enter the Range: ";
    cin>>numOne>>numTwo;
    if(numTwo>numOne)
    {
        cout<<"--------Table from "<<numOne<<" to "<<numTwo<<"--------\n\n";
        for(i=numOne; i<=numTwo; i++)
        {
            num = i;
            cout<<"Table of "<<num<<": ";
            for(j=1; j<=10; j++)
            {
                res = num*j;
                cout<<res<<"  ";
            }
            cout<<endl;
        }
    }
    else
    {
        cout<<"--------Table from "<<numTwo<<" to "<<numOne<<"--------\n\n";
        for(i=numTwo; i<=numOne; i++)
        {
            num = i;
            cout<<"Table of "<<num<<": ";
            for(j=1; j<=10; j++)
            {
                res = num*j;
                cout<<res<<"  ";
            }
            cout<<endl;
        }
    }
    cout<<endl;
    return 0;
}

Here is a sample run with user input, the first number being 20 and the second being 6:
