Erase the current printed console line
You can use VT100 escape codes. Most terminals, including xterm, are VT100 aware. For erasing a line, this is ^[[2K. In C this gives: printf(“\33[2K\r”);

Erasing elements from a vector
Use the remove/erase idiom: std::vector<int>& vec = myNumbers; // use shorter name vec.erase(std::remove(vec.begin(), vec.end(), number_in), vec.end()); What happens is that remove compacts the elements that differ from the value to be removed (number_in) in the beginning of the vector and returns the iterator to the first element after that range. Then erase removes these elements … Read more
C++ Erase vector element by value rather than by position? [duplicate]
How about std::remove() instead: #include <algorithm> … vec.erase(std::remove(vec.begin(), vec.end(), 8), vec.end()); This combination is also known as the erase-remove idiom.
How do I erase an element from std::vector by index?
To delete a single element, you could do: std::vector<int> vec; vec.push_back(6); vec.push_back(-17); vec.push_back(12); // Deletes the second element (vec[1]) vec.erase(std::next(vec.begin())); Or, to delete more than one element at once: // Deletes the second through third elements (vec[1], vec[2]) vec.erase(std::next(vec.begin(), 1), std::next(vec.begin(), 3));
