Diagonal Star Pattern in C

#include <stdio.h>

int main()
{
  int i, j, rows;

  printf("Enter the no. of rows: ");
  scanf("%d", &rows);

  int m = (2 *rows) - 1;

  for (i = 1; i <= m; i++)
  {
    for (j = 1; j <= m; j++)
    {
      if (i == j || j == (m - i + 1))
        printf("*");
      else
        printf(" ");
    }
    printf("\n");
  }

  return 0;
}
