# Step by Step solution

  1. Number of row

    Is has 5 row , so first loop will execute for 5 time

#include <stdio.h>
int main()

{

    int i, j;

    for(i=5;i>=1;i--)
    
{......
 }



    return 0;

  1. Number of character

It has only one type of character , so there will be only one nested loop

#include <stdio.h>
int main()

{

......
 for(j=i;j<=5;j++)
        {
            printf("%d",j);
        }
        printf("\n");

  1. Number of column

It has 5 maximum column and is decreasing with row number , so the nested loop decrease it's repetation with increase in row

#include <stdio.h>

............
     for(j=i;j<=5;j++)
        {
            printf("%d",j);
        }
        printf("\n");
...................


    return 0;
