strcpy

Your mission

Write gm_strcpy, your own strcpy, which copies the source string into the destination buffer.

See it in action

gm_strcpy(dst, "hello")

Expected result

dst contains `hello`

Your checklist

For your own tracking. Tests grade your code.

Copy characters from src into dst in order.
Include the terminating null byte in the copy.
Return dst once the copy is complete.

Constraints

Expected files

strcpy.c

Allowed functions

None. Write every helper yourself.

libc

Standard C library

Implements the contract of a function from the standard C library.
