[Solved] Question on data types

[zodiac976]

I just got to thinking about how I set up my variables
and I want to know if it is okay to use string variables
for everything and convert them when I need to calculate.
I liked using strings for almost everything so I can rely on
getline() and using fstream or maybe I should just do it the
other way, declare them as integer, double, char, etc and
then convert them?

Declare what you need. If you want to enforce a datatype input, or if you're expecting a certain datatype as input, use cin with your specified datatype and check for cin failure to see if you got the type that you needed (and do a[getline() or .ignore() or .sync() to remove the trailing \n). If cin.fail() is true, do a .sync() to remove all unread characters from the input buffer, and follow it with cin.flush(), to remove the failure flag. On the other hand, if you really need string manipulation, declare your input variables as strings. But, as you can see, there are better ways to validate than by using a string.

I see thank you for the input .

scanf FTW!

Just putting that out there

Isn't that for C and not C++?

but you are free to use it, I tend to use strlen() instead of string.length(), because it's just plain easier

Yep, but I am so used to strings and I always use .length() .
