    For loop behaving unexpected!!

    Here is my code to take 6 integers into an array (But taking 24 entries don't know how??):

    Code:
    #include <stdio.h>
    #include <stdlib.h>
    
    
    void main()
    {
        int arr[6], counter, length;
        system("clear");
        
        printf("\nEnter elements of array: \n");
        
        length = sizeof(arr);
        for (counter = 0; counter < length; counter++)
        {
            printf("Array element %d : ", (counter+1));
            scanf("%d", &arr[counter]);
        }
        
        getchar();
        
    }

    Sizeof(arr) counts bytes, not ints.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Code:
    printf("%d\n", ( sizeof(arr)/sizeof(arr[0]) ));
