#include <string.h>

int main()
{
    char arr1[] = "abcdef";
    char arr2[] = "bit";
    strcpy(arr1, arr2);
    printf("%s", arr1);
    return 0;
}

#include <string.h>


char* my_strcpy(char* dest, char* scr)
{
    assert(dest != NULL);
    assert(scr != NULL);
    char* ret = dest;
    while (*dest++ = *scr++)
    {
        ;
    }
    return ret;
}

int main()
{
    char arr[] = "abcdefghij";
    char arr1[] = "bit";
    my_strcpy(arr, arr1);
    printf("%s",arr);
