Hello,

How do I take input via cin, but only accept numerical input and not letters and symbols in C++? Surprisingly this is harder than I thought, but I suppose after working with C# I just got use to the built in libraries to handle this.

Edit: Oh yeah the variable type would be a double so what I'm trying to do is


double NUMBER = NULL;

cin >> NUMBER;
