Print pattern in c - number pattern

Write a program to print following pattern

1
21
321
4321
54321

Program code

#include <stdio.h>

int main()
{
    int i, j;
    for(i=1;i<=5;i++)
    {
        for(j=i;j>=1;j--)
        {
            printf("%d",j);
        }
        printf("\n");
    }

    return 0;
}

Step by Step solution

1. Number of row -

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

#include <stdio.h>
int main()

{

    int i, j;

    for(i=1;i<=5;i++)
    
{......
 }



    return 0;

}

2. 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>=1;j--)
        {
            printf("%d",j);
        }
        printf("\n");
}

3.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>=1;j--)
        {
            printf("%d",j);
        }
        printf("\n");
...................


    return 0;

}
