How do I return a char array from a function?

Question

I\'ve tried the following:

char[10] testfunc()
{
    char[10] str;

    return str;
}

Answer 1

a char array is returned by char*, but the function you wrote does not work because you are returning an automatic variable that disappear when the function exits. Use something like this:

char *testfunc() {
    char* arr = malloc(100);
    strcpy(arr,"xxxx");
    return arr;
}

This of course if you are returning an array in the C sense, not an std:: or boost:: or something else. As noted in the comment section: remember to free the memory from the caller.
