PLEASE HELP!!! diagonal output?

Please help me, I am really having a hard time to program these:

1. Write a program that input integer and displays the digits diagonally.
Ex. Entered number: 3562
output: 3
5
6
2

2. Write a program that read in a number n and then outputs the sum of the aquares of the number n and then outputs the sum of the squares of the numbers from 1 to n. if the input is 3, for example, the output should be 14. The program should allow the user to repeat this calculation as often as desired.

--------------------------------------------------------------------
I tried solving it but there are always errors. I think looping is needed to solve that. And how to display the output diagonally?
pls help.

Here's what ive tried for number 1:

Code:

---

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

void main () {

char string[256]:
printf("input nuber: \n");
scanf("%s", &number);

printf("%s", string);

getch();
}

---

I know that it is not right but that is the only idea i have.

PLEAS HELP.
This kind of question is included in our exam.

im sorry, the output of number should be in diagonal. the example misfunctioned.

Read the numbers into a string, and output it using a loop.

is that already correct? We haven't discussing that lesson yet. I have just do lots of research. :(

Code:

---

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

void main () {

char string[256]:
printf("input nuber: \n");
scanf("%if", &string);

printf("%if", string);

getch();
}

The input part is right, but you need to output it with a loop, treating the string as an array (instead of a string).

1. void main is wrong. USe int main(void) instead.
2. What is %if?
3. string itself is an address, so you dont need '&' with it in scanf().
4. Note the colon(instead of ; ) in the first line after main.

My solution will be :
1.Input the string.
2. Print the chars of the string using width specifiers of varying width. That will output the chars of the string in diagonal format.
