How can I print a character N number of times using std::cout without looping?

Is there a way to move the text cursor back to nullify the effect of std::cout << std::endl;? i.e. to move up a line (say we never printed anything after doing the std::cout << std::endl; operation).

 std::cout << std::string(100, '*') << std::endl;

To move a line up, you have to resort to terminal escapes (assuming that isatty() indicates that you are running on one).
