Error in return value type in function in C

Question

I need to implement the strcpy source in C.

I dont understand why am i have this eror in line 15 (in the line- "return saved;"):

Error: return value type does not match function type

this is the full source:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <stdarg.h>


char str_cpy(char *d, const char *s)
{
    char *saved = d;
    while (*s)
    {
        *d++ = *s++;
    }
    *d = 0;
    return saved; // line 15. here the eror
}

int main(int argc, char *argv[])
{

}

Answer 1

You are returning saved which is of type char *, so declare you're function returning char * as,

char * str_cpy(char *d, const char *s)

Answer 2

You declared your function to return char and you return char*.

Change the function signature to return char*.

char* str_cpy(char *d, const char *s)
