Reading numbers from console

Hi guys, I'm new to the forum.

I'm new to C and have only ever programmed in Java, therefore having a bit of problems at the moment.
I'm trying to write a program that reads ten numbers from the keyboard, stores
them in an array of integers and then prints out the numbers in the reverse order.

I have done this so far:

Code:

---


#include <stdio.h>
#include <stdlib.h>

main()
{
        int arr[10];
        int BUFFSIZE = 10;
        char buffer[BUFFSIZE];

        int i=0;
        int *pa;

        int z=9;
        int a;

        while (i<10){

        printf("Enter an integer:\n");
        fgets(buffer,BUFFSIZE,stdin);

        if ( feof(stdin)){
                printf("Finished\n");
                break;
        }
        arr[0]= atoi(buffer);

        i++;
        }


        while(z>=0){
                pa=&arr[z];
                a=*pa;
                printf(a);
                z--;
        }

}

---

I do not really understand where i am going wrong (maybe because i might not fully understand pointers yet). Also I do not understand why the feof function is needed in this case.

Any help would be really appreciated.

Thanks

simple code to demonstrate an array of integers

Code:

---

#include <stdio.h>

int main() {
  int arr[10] = {0};
  int index = 0;

  for (; index < 10; ++index) {
    printf("Please enter %d number\n", index + 1);
    scanf("%d", &arr[index]);
  }

  // Display numbers                                                                                                                                                                                             
  index = 0;
  for (; index < 10; ++index)
    printf("%d  ", arr[index]);

  return 0;
}

Neither do I. That condition will never be met, so this is meaningless:

Code:

---

        if ( feof(stdin)){
                printf("Finished\n");
                break;
        }

If you want to check the user's input (to see if they just pressed enter with no number) you need to examine what's in "buffer".

Your problem is a malformed printf. Look at RockM's example.

Thanks everyone, I have managed to sort it out now. Really much appreciated
