displaying times table from 1 to 12 in c

Question

I'm a novice in c programming. I recently started while loop in c. Now I'm trying to display times table from 1 to 12 using while loop in c programming. I would be very delighted  the problem if anyone would explain to me how to do it and with detailed explanation  I want output like this:

Times table from 1 to 12:

 1 2 3  4    5  6    7   8   9 10

 2 4 6  8  10 12 14 16 18 20

3 6 9 12 15  18 21 24 27 30

......

......

......

12 24 48 60 72 84 96 108 120

Answer 1

#include <stdio.h>

int main(){
    int num = 12;
    int i, j;
    int res;
    for(i=1;i<=12;i++){
        for(j=1;j<=10;j++){
            res = i*j;
            printf("%d\t",res);
        }
        printf("\n");
    }

    return 0;
}

Answer 2

#include <stdio.h>

int main()
{
   int i,j,res;

printf("multipli Table:");
for(i=1;i<=10;i++)
{
    for(j=1;j<=10;j++)
    {
        res=i*j;
     printf("%d\t",res);
     
}
printf("\n");
        
    }

return 0;

}

Answer 3

#include <stdio.h>
#include <string.h>

void                /* params: maxcolums, currentcolumn, currentrow, column separator, column width */
dumpcol (int mc, int c, int r, char s, int cw)
{
  if (c < mc)
    {
      char fs[9];
      sprintf (fs, "%%%dd%%c", cw);
      if (c == mc - 1)
    sprintf (fs, "%%%dd", cw);
      printf (fs, ++c + mc * r, s);
      dumpcol (mc, c, r, s, cw);
    }
}

void                /*params: maxcolums, maxrows, currentrow, column separator, column width, lineseparator */
dumptable (int mc, int mr, int r, char s, int cw, char *ls)
{
  dumpcol (mc, 0, r, s, cw);
  printf ("%s", ls);
  if (++r < mr)
    dumptable (mc, mr, r, s, cw, ls);
}

int
main ()
{
  dumptable (10, 12, 0, ' ', 3, "\n");
  return 0;
}
