You are merely copying the starting address of str to temp. This means that any changes to temp will be reflected in str as well, since they point to the same memory. It does not truly emulate strcpy(dest, src), which creates a separate copy of the null-terminated string pointed to by src starting at the memory location pointed to by dest.
So, to answer your question as asked: no.
If your intent is to avoid the O(n) running time of strcpy, that's also something you can't really do.
If you're required by a programming assignment or exercise to create code functionally equivalent to strcpy, here is a high-level description of the algorithm it uses:
- Copy the character in
*sourceto*destination - If the character that was just copied was the null terminator, exit.
- Otherwise, increment the pointer to
source, and increment the pointer todestination. - Go to step 1.

Copy String without using strcpy
Well, gee, it's sure a good thing you did that, because none of us knew how. I mean, the only reason we didn't just post full working code is because we couldn't figure it out. Oh, and your code is wrong. The second string won't have a null terminator, and when you try and use it, you'll merrily run off the end of your array.

C Program to Copy One String to Another
As you can see from the above snapshot, only "codes" are initialized in the variable str1, and the value of str1 gets copied to the str2 variable. Therefore, the above program is correct only when the user doesn't supply any strings with spaces. This program performs the same function as the previous one, but without the use of the library function strcpy():
