Need some help with TmpArray()

[invoker]

Hello everyone!
Today I am in need of assistance with some code usage.

char TmpArray[hello world!]; 
std::string

I am working on a project with it and need to know how it works.

My teacher said to look about arrays and the standard template library string. A link to documentation for this would be helpful.

Well, it looks like you've declared a character array called TmpArray.

The std::string on its own after that declaration makes no sense, though.

Character arrays:
http://cplusplus.com/doc/tutorial/ntcs/

char hello1[] = "Hello, World!"; // automatic size, just enough to fit the message
char hello2[200] = "How's it going?"; // size is 200, no matter the message 

STL std::string:
http://cplusplus.com/reference/string/string/

#include <string>

std::string hello("Hello, World!");

As a C++ programmer, you should favor using std::string (also called "C++ strings") instead of character arrays (also called "C strings").

std::string is easier to use, knows its own size, can be resized, etc.
