Multiplication table till N rows where every Kth row is table of K upto Kth term

Given a number N, the task is to print N rows where every Kth row consists of the multiplication table of K up to Kth term.

Examples:

Input: N = 3
Output:
1
2 4
3 6 9
Explanation:
In the above series, in every Kth row, multiplication table of K upto K terms is printed.



Input: N = 5
Output:
1
2 4
3 6 9
4 8 12 16
5 10 15 20 25

Approach: The idea is to use two for loops to print the multiplication table. The outer loop in ‘i’ serves as the value of ‘K’ and the inner loop in ‘j’ serves as the terms of the multiplication table of every ‘i’. Each term in the table of ‘i’ can be obtained with the formula ‘i * j’.

Below is the implementation of the above approach:

#include <iostream>
using namespace std;
  
// Function to print the multiplication table
// upto K-th term
void printMultiples(int N)
{
    // For loop to iterate from 1 to N
    // where i serves as the value of K
    for (int i = 1; i <= N; i++)
    {
  
        // Inner loop which at every
        // iteration goes till i
        for (int j = 1; j <= i; j++)
        {
  
            // Printing the table value for i
            cout << (i * j) << " ";
        }
  
        // New line after every row
        cout << endl;
    }
}
  
// Driver code
int main()
{
    int N = 5;
  
    printMultiples(N);
  
    return 0;
}
