Thread: Loop

Hi
I want the program to take in a number n, and then print n,n-1,n-2 till 1
the next line, it should start from n-1,n-2 till 1
then n-2,n-3 till 1

eg n=5, then
54321
4321
321
21
1

I tried but it doesnt work as I though.

Code:

#include<stdio.h>
#include<conio.h>
void main()
{
int n,i=0;
clrscr();
printf("Enter value of N\n");
scanf("%d",n);
while(n!=0)
 {
 for(i=n;i>=1;i--,n--)
 {
 printf("%d",i);
 printf("\n");
 }
}
getch();
}

any help?

You probably only want n to go down once per line, not one time for every digit printed.

fixed it

Code:

#include<stdio.h>
#include<conio.h>

void main()
{
int n, row,col;
clrscr();
printf("enter n\n");
scanf("%d",&n);
for(row=n; row>=1; row--)
 {
 for(col=row; col>=1; col--)
 {
 printf("%d ",col);
 }
 printf("\n");
 }

for(row=1; row<=n; row++)
 {
 for(col=1; col<=row; col++)
 {
 printf("%d ",col);
 }
 printf("\n");
}
getch();

}
