Please provide *complete* testcases, this code is missing <stdio.h> and
<string.h>, since you already wrote it so it compiles why should we have to add
headers again to test it?

the array elements will be uninitialized

This is undefined behaviour, there is no null terminator in the array, how is
strlen supposed to find the length?
