Re: Pass a string by reference

Passing by reference only means to pass a pointer, and all arrays are always passed by reference, never by value.

It is not necessary to pass a pointer to a pointer. Passing by reference means to pass a pointer, and String is already a pointer. All that function needs is a pointer to the allocated memory where to do the concantination. Its not necessary to change the value of the original pointer that was allocated in main().

void string_concat( char *string )  {
    
    //write in string something, need a realloc?
    strcat(string, something);
