Thread: 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;
}

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