I can't seem to use the 'cin.get' statement for getting character arrays. I've just switched to VC++ Express, from Dev-Cpp, which allowed that. I have tried other methods like declaring the variable with 'string' but the compiler doesn't recognise it even with the <string> header. [code] void encrypt() { string …
