I need to read in a value (cin) including a dollar sign and a dollar amount, but I only want to read in the amount.
In other words, I have this input:
but I want to read in and store
The current approach I thought of was reading the value in as a string, removing the first character, and then converting to a double. But, I feel like this method is inefficient and there's a better method out there. Any tips? Thanks!
I agree with Magnus: this seems minor. But if you really want to do it, just read a character then read a double:
char ch; double d; std::cin >> ch >> d;
