Thread: Issue with Pointer

hey everyone!

having a small problem with my pointer.
I'm just trying to scan an array using a pointer but when i print it it shows me only zeros. Any help?

Code:

#include <stdio.h>


int main()
{
    int arr[10];
    int *ptr;
    int i;
    
    ptr = &arr[0];
    printf("Enter 10 integers:\n");
    for (i=0; i<5; i++){
        printf("arr[%d]: ", i);
        scanf("%d", ptr);
        ptr++;
    }
    
    for (i=4; i>=0; i--) {
        printf("arr[%d] = %d\n", i, *(ptr+i));
    }
    
}

got it!

Code:

#include <stdio.h>

int main()
{
    int arr[10];
    int *ptr;
    int i;
    
    ptr = &arr[0];
    printf("Enter 10 integers:\n");
    for (i=0; i<5; i++){
        printf("arr[%d]: ", i);
        scanf("%d", ptr);
        ptr++;
    }
    ptr = &arr[4];
    
    for (i=4; i>=0; i--) {
        printf("arr[%d] = %d\n", i, *ptr);
        ptr--;
    }
    
}
