A simpler solution is to the pass a size_t argument by reference (i.e. This prints correctly, but by making it static I may as well have made it a global variable. You can return a pointer to a char array. For most (not all) purposes in C, char* is the same type as char[] If you want to return a char array from a function, you should declare the function as returning char* not char. But you seem intent on returning the contents of a char array, rather than the pointer that the C language pretends is the same type as the array. Actually, why not have the caller pass a … Second point to remember is that C++ does not advocate to return the address of a local variable to outside of the function so you would have to define the local variable as static variable. Answer (1 of 28): The thing about arrays is that A. Arrays do not carry around their size. Notice you're not dynamically allocating the variable, which pretty much means the data inside str , in your function, will be lost by the end of...

The return to the calling program will be –1 in the event that the character array was completely filled. The struct field name is on the stack as well, so the address you return is an address on the stack, where the struct was copied to. char a[2] ; But it is not recommended to return the address of a local variable outside the function as it goes out of scope after function returns.

Creating a game - limited time to learn (being a father etc) which engine? D. Array names decay into pointers. I am currently rewriting horrible looking test code and trying to get some functions to clean up, but I'm running into the issue where I must have arrays not pointers returned to be able to manipulate the data being processed. That's a pointer to a character array, not the whole array - and you can't return a whole array. What type do I even use for the function?
