Problem Statement:- Program to Print the V Shape Number Pattern.

 Data requirement:-

  Input Data:- row_size

  Output Data:- out

  Additional Data:-in or inn(for python), print_control_x, print_control_y

Program in C

Here is the source code of the C Program to Print the V Shape Number Pattern.

Code:

#include <stdio.h>
int main()
{
  int out, in;
  printf("Enter the row size:");
  int row_size;
  scanf("%d", &row_size);
  int print_control_x = 1;
  int print_control_y = row_size * 2 - 1;
  for (out = row_size; out >= 1; out--)
  {
    for (in = 1; in <= row_size * 2; in++)
    {
      if (in == print_control_x || in == print_control_y)
      {
        printf("%d", out);
      }
      else
      {
        printf(" ");
      }
    }
    print_control_x++;
    print_control_y--;
    printf("\n");
  }
}

Input/Output:

Enter the row size:5
