c++ - 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

Best as an out parameter:

void testfunc(char* outStr){
  char str[10];
  for(int i=0; i < 10; ++i){
    outStr[i] = str[i];
  }
}

Called with

int main(){
  char myStr[10];
  testfunc(myStr);
  // myStr is now filled
}
