(C++) std::strcpy

The standard function std::strcpyt copies char*'s (i.e. C-style-strings, or null-terminated strings).

The example below copies a char* over another.

include <cstring>

include <cassert>


int main()
{
  char * const name1 = "Bilderbikkel";
  char * const const name2 = "was here....";
  //assert(name1=="Bilderbikkel"); //Won't work, only for std::strings
  assert(std::strcmp(name1,"Bilderbikkel")==0);
  //Copy name2 over name1
  std::strcpy(name1,name2);
  //assert(name1=="was here...."); //Won't work, only for std::strings
  assert(std::strcmp(name1,"was here....")==0);
}

Use std::string instead of an array of char [1,2].
