Troubleshooting "cout was not declared in scope" with XCode

AI Thread Summary
In C++, the 'std::' prefix is necessary when using standard library components like 'cout' and 'cin' due to the language's namespace feature. Namespaces help organize code and prevent naming conflicts by grouping related functions and variables. The error message indicating that 'cout' was not declared in scope typically arises when the 'std::' namespace is not specified. Resources are available online for further understanding of namespaces, and users are encouraged to ask specific questions if they need clarification. The discussion highlights the learning opportunity presented by namespaces, which may not have been covered in earlier programming education.

std:: was not used in my previous experiences with programming in C/C++ but in xcode,it requires you to put 'std::' in front of both cout and cin. i get an error that reads 'cout' was not declared in scope. I am sure it is something very trivial but in insights would be appreciated.

C++ has the concept of "namespaces". In standard C++, all functions and global variables must be declared within some namespace. I hope you'll forgive me for not taking the time to write a long tutorial on namespaces when there is a lot of material about namespaces available already, for example with a Google search on "C++ namespaces".

After doing some reading, if you have specific questions, please feel free to ask here!
 
thanks for the help!

namespace was not a concept i remember from my programming classes so it was nice to learn something new. :)

Thread 'Is this public key encryption?'

I've tried to intuit public key encryption but never quite managed. But this seems to wrap it up in a bow. This seems to be a very elegant way of transmitting a message publicly that only the sender and receiver can decipher. Is this how PKE works? No, it cant be. In the above case, the requester knows the target's "secret" key - because they have his ID, and therefore knows his birthdate.

Thread 'Project Documentation'

Thread 'Project Documentation'

Trying to package up a small bank account manager project that I have been tempering on for a while. One that is certainly worth something to me. Although I have created methods to whip up quick documents with all fields and properties. I would like something better to reference in order to express the mechanical functions. It is unclear to me about any standardized format for code documentation that exists. I have tried object orientated diagrams with shapes to try and express the...
