Global variable help

Tyler1234

I need to make a variable and have it be assessable form all my .cpp files. how do I do this?

Or a way to send a variable to another file so it can be accessed.

Hi,

There are several techniques for that but it's generally discourage. Why do you need that global variable ?

I have a person login to an account and then I need to detect which account the person logged into, but the account number is on one cpp file and The place I need to check is on another cpp file, so I need to make a way to acsess the variable from both cpp files

Then you should rather look after the singleton pattern

nnead

you could try to solve your problem by single/slot mechanism, just connect your login with both .cpp files

@connect(client,SIGNAL(login()),this,SLOT(check4id()));@

Could you explain more on how to do this?
