Consider a scenario where a console application asks for a series of inputs, one after the other. Each input is validated before proceeding to the next. Now if an input made by the user is invalid, an error message is shown and the user is asked if he/she wants to continue. If the user chooses no, the input process is aborted. If the use...
Presently, I am using the following function template to suppress unused variable warnings: template<typename T> void unused(T const &) { /* Do nothing. */ } However, when porting to cygwin from Linux, I am now getting compiler errors on g++ 3.4.4 (On linux I am 3.4.6, so maybe this is a bug fix?): Write.cpp: In member function `vo...
