[ask]pyramid number with loop

Code:

---

#include<stdio.h>
main()
{
int a,b,c;
clrscr();
 printf("input : ");scanf("%d",&c);
        for(a=1; a<=c; a++)
        {
                for(b=1; b<=a; b++)
                        printf("%d",b);
                        printf("\n");
        }
getch();
}

---

Output :
1
12
123

I try to make it like this:

1
12
123
12
1

but i always get this :

1
3
12
3
123
3

You need to count up, and then back down. So...

Code:

---

for each row on the way up
    for each column on the way up
        print number
    print newline

---

Then do the same thing for the way back down. (Hint: Don't reset the values of a and b, and count down.
