C++ Tutorial 2: Variables and Operators

This video talks about the basic tools for storing data and processing it.

One small derp, you called the forward slash for division a backslash. You drew it correctly so it must just be tiredness :)

in java they're objects, but in c++ string is a keyword. in c++ a "string" is essentially a "char[]", but it is a type nonetheless

How do you concatenate string variables in C++? I can concatenate strings, but when I store strings in variables and then concatenate them in the cout statement I get a confusing error message. Here's what I've written:

string name = "World";
cout << "Hello, " << name << "!" << endl;

And I get a weird error that says no operator "<<" matches these operands.

Loads of info and "yeah's "  ;) :D

when you were talking about variable types you missed them out, and i'm pretty sure they're very commonly used.

[SamBrev]

yes, but a string functions like a char array in every way. you can find a char in a string by calling string[int] - the same as a char array. you can get the length by going string.length - the same as a char array. they are practically the same in c++

Ah, no, they are both in C++. You can use char* or std::string.
