Working on code for a custom number class: number & number :: operator+(const number &rhs) { this -> add(rhs); return *this; } number & number :: operator=(const number &rhs) { if (this != &rhs) // with equal, need to check for self-references { delete this; // deallocate what we currently have memcpy(this, &rhs, sizeof(number)); // replace with copy } return *this; } Useful links: * http://stackoverflow.com/questions/3279543/what-is-the-copy-and-swap-idiom * http://courses.cms.caltech.edu/cs11/material/cpp/donnie/cpp-ops.html ======Month Status Page Navigation====== ^ [[haas/status/status_201510|Previous Month]] ^ [[haas/status|Current Month]] ^ [[haas/status/status_201512|Next Month]] |
