Turning a varible into a global.
But, sense nVarry was declared inside of a function, a different function cannot read nVarry. So my question is, how can I make a varible (in this case 'nVarry') become a global varible so that it can be read through out the whole app, and not just inside of the brackets that it was created in?Code:void make(hwnd HWND) { int nVarry = 90; } void read(hwnd HWND) { if(nVarry == 90) Beep(2000,100); }
Thanks in advance, August.
Well, there are usually better methods than creating global variables, but to create one, you simply need to declare it outside the scope of any functions/classes. So, at the top of your file (generally below header includes -- stylistic issue), just declare it: 'int nVarry;'.

The word rap as it applies to music is the result of a peculiar phonological rule which has stripped the word of its initial voiceless velar stop.
You don't wan tto make it global, why don't yo upass nVarry to each of the functions? Or make those functions members of a class and nVarry a member of it?
