Recursive Program to print multiplication table of a number
  • Difficulty Level : Hard
  • Last Updated : 05 Apr, 2021

Given a number N, the task is to print its multiplication table using recursion
Examples 
 

Input: N = 5 
Output: 
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
Input: N = 8 
Output: 
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 
 

 

 

Recursive approach to print multiplication table of a number



Approach: 
 

  1. Get the number for which multiplication table is to print.
  2. Recursively iterate from value 1 to 10: 
    • Base case: If the value called recursively is greater than 10, exit from the function. 
       
if(i > N) 
  return ;
  •  
  • Recursive call: If the base case is not met, then print its multiplication table for that value and then call the function for next iteration. 
     
print("N*i = ", N*i)
recursive_function(N, i+1);
  •  
  • Return statement: At each recursive call(except the base case), return the recursive function for next iteration. 
     
return recursive_function(N, i+1);
  •  

Below is the implementation of the above approach:
 

C++




// C++ program to print table
// of a number using recursion
#include <iostream>
using namespace std;
 
// Function that print the
// table of a given number
// using recursion
void mul_table(int N, int i)
{
    // Base Case
    if (i > 10)
        return;
 
    // Print the table for
    // current iteration
    cout << N << " * " << i
         << " = " << N * i
         << endl;
 
    // Recursive call to next
    // iteration
    return mul_table(N, i + 1);
}
 
// Driver Code
int main()
{
    // Input number whose table
    // is to print
    int N = 8;
 
    // Function call to print
    // the table
    mul_table(N, 1);
    return 0;
}

Java




// Java program to print table
// of a number using recursion
class GFG {
     
    // Function that print the
    // table of a given number
    // using recursion
    static void mul_table(int N, int i)
    {
        // Base Case
        if (i > 10)
            return ;
     
        // Print the table for
        // current iteration
        System.out.println(N + " * " + i + " = " + N * i);
                
        // Recursive call to next
        // iteration
        mul_table(N, i + 1);
    }
     
    // Driver Code
    public static void main (String[] args)
    {
        // Input number whose table
        // is to print
        int N = 8;
     
        // Function call to print
        // the table
        mul_table(N, 1);
    }
}

Python3




# Python3 program to print table
# of a number using recursion
 
# Function that print the
# table of a given number
# using recursion
def mul_table(N, i):
     
    # Base Case
    if (i > 10):
        return
     
    # Print the table for
    # current iteration
    print(N,"*",i,"=",N * i)
     
    # Recursive call to next
    # iteration
    return mul_table(N, i + 1)
 
# Driver Code
 
# Input number whose table
# is to print
N = 8
 
# Function call to print
# the table
mul_table(N, 1)

C#




// C# program to print table
// of a number using recursion
using System;
 
class GFG{
     
    // Function that print the
    // table of a given number
    // using recursion
    static void mul_table(int N, int i)
    {
        // Base Case
        if (i > 10)
            return ;
     
        // Print the table for
        // current iteration
        Console.WriteLine(N + " * " + i + " = " + N * i);
                
        // Recursive call to next
        // iteration
        mul_table(N, i + 1);
    }
     
    // Driver Code
    public static void Main()
    {
        // Input number whose table
        // is to print
        int N = 8;
     
        // Function call to print
        // the table
        mul_table(N, 1);
    }
}

Javascript




<script>
 
// Javascript program to print table
// of a number using recursion
 
// Function that print the
// table of a given number
// using recursion
function mul_table(N, i)
{
    // Base Case
    if (i > 10)
        return;
 
    // Print the table for
    // current iteration
    document.write(N + " * " + i
         + " = " + N * i
         + "<br>");
 
    // Recursive call to next
    // iteration
    return mul_table(N, i + 1);
}
 
// Driver Code
 
// Input number whose table
// is to print
var N = 8;
 
// Function call to print
// the table
mul_table(N, 1);
 
</script>
Output: 
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
