Multiplication table#8545

Multiplication table (Megoldási útmutató)

Use a nested loop to print the multiplication table.

Algorithm implementation

Read the input value $n$ .

scanf("%d",&n);

Using a double loop, print the multiplication table. To ensure alignment, each number should occupy two positions. Use the $%2 d$ format for output.

for (i = 1; i <= n; i++)
{
  for (j = 1; j <= n; j++)
    printf("%2d ", i * j);
  printf("\n");
}

Java implementation

import java.util.*;

public class Main
{
  public static void main(String[] args)
  {
    Scanner con = new Scanner(System.in);
    int n = con.nextInt();
    int m[][] = new int[n+1][n+1];

    for(int i = 1; i <= n; i++)
    for(int j = 1; j <= n; j++)
      m[i][j] = i * j;

    for(int i = 1; i <= n; i++)
    {
      for(int j = 1; j <= n; j++)
        System.out.printf("%2d ", m[i][j]);
      System.out.println();
    }
    con.close();
  }
}

Java

Python implementation

Read the input value $n$ .

n = int(input())

Using a double loop, print the multiplication table. To ensure alignment, each number should occupy two positions. Use the $%2 d$ format for output.

for x in range(1, n + 1):
  for y in range(1, n + 1):
    print("%2d" %(x * y), end=' ')
  print()
