Answer 1

Answer:

This is the required C program for the question.

#include <stdio.h>

int main () {

int i,j,n;

printf("Enter number of rows - ");

scanf("%d",&n);

printf("Here is your pattern.\n");

for(i=n;i>=1;i--) {

for(j=i;j>=1;j--)

printf("%d ",j);

printf("\n");

}

return 0;

}

Algorithm:

1. START.
2. Accept the number of rows(n).
3. Iterate outer loop in range - i = n to 1.
4. Iterate inner loop in the range j = ito 1.
5. Print the value of j.
6. Print a new line after displaying the row.
7. STOP.
