How to create a multiplication table in C++

This is a C++ tutorial where we will learn how to create a multiplication table. We will accomplish this using a for loop in C++, however you can use while or do while loop also. Multiplication table for a number is often written till 10 but in this tutorial, we will do it for a specified range input too.

Creating a multiplication table in C++

Here we can create two types of multiplication table:

• Without range
• With a given range

Let’s explore one by one

If the range is not given:

If there is only one input specifying the number for which we have to create the multiplication table, then we will follow the below process:

• Accept the input (Integer) from the user and store it in a variable.
• Create a for loop and iterate it 10 times.
• For every iteration, multiply the variable with the iterating integer and print the output. Make sure the iterating integer starts with 1 and iterates 10 times.

 

Here is the code: Multiplication table in C++

#include <iostream>
using namespace std;

int main()
{
  int i,a;
  cin>>a;
  for(i=1;i<=10;i++)                                
  {
    cout<<a<<" x "<<i<<" = "<<(a*i)<<endl;
  }
  return 0;
}

Output:

5
5 x 1 = 5
5 x 2 = 10
5 x 3 = 15
5 x 4 = 20
5 x 5 = 25
5 x 6 = 30
5 x 7 = 35
5 x 8 = 40
5 x 9 = 45
5 x 10 = 50

Explanation:

In this example code, input given by the user is 5 and it is stored in the variable a. In the next step, we have created a for loop with iterating integer i which is starting from 1. The loop ends when the condition (i<=10) is not satisfied that is the statement inside the loop is executed only till (i=10).

If the range is given: Create a multiplication table in C++

If the range is given for the multiplication table then, we will take two integer inputs from the user and based on that we will show the output.

• The first input should be the number for which we have to create the multiplication table.
• The second input should be a number that specifies the range of the table.
• Again, we need to create a for loop and iterate it as many times as the value given by the second input.
• For every iteration, multiply the first input with iterating integer and print the output. Make sure iterating integer starts with 1.

 

Multiplication table in a given range in C++

#include <iostream>
using namespace std;

int main()
{
  int i,a,b;
  cin>>a;
  cin>>b;
  for(i=1;i<=b;i++)
  {
    cout<<a<<" x "<<i<<" = "<<(a*i)<<endl;
  }
  return 0;
}

 

Suppose the input given by the user is this:

3
7

Then the output will be like this:

3 x 1 = 3
3 x 2 = 6 
3 x 3 = 9 
3 x 4 = 12 
3 x 5 = 15 
3 x 6 = 18 
3 x 7 = 21

Explanation:

Here, the user has entered two inputs. 3 and 7. 3 is stored in variable a and 7 is stored in variable b. Then, we have used a for loop with its iterating integer starting with 1. Now, the statement inside the loop is executed as long as the condition (i<=7) is satisfied that is multiplication operation is done only till (i=7).

   how we can adjust its starting range? if I start it from any number for (from 5)

     Set the starting range with input variable
