After you modify the ptr, you miss the first element address of the array. You need to reassign the first element address before entering the printer loop. See the fixed code:

#include <stdio.h>

int main()
{
    int arr[5];
    int *ptr = arr; // You can assign an array of the first element directly using the identifier.
    for (int i = 0; i < 5; i++) {
        printf("enter the value of array at place %d : ", i + 1);
        scanf("%d", ptr);
        ptr++;
    }
    ptr = arr; // This line was missing
    for (int i = 0; i < 5; i++) {
        printf("value of array at place %d is %d\n", i + 1, *(ptr + i));
        // ptr++;
    }

    return 0;
}
