this is my first question on stack overflow, so be gentle. Let me first explain the exact behavior I would like to see. If you are familiar with C# then you know that declaring a variable as \"readon
I wonder about the use of the static keyword as scope limiting for variables in a file, in C. The standard way to build a C program as I see it is to:
... #include \"test1.h\" int main(..) { count << aaa <<endl; } aaa is defined in test1.h,开发者_C百科and I didn\'t use extern keyword,but still can reference aaa.
In my MyConstants.h file... I have: int abc[3]; In my matching MyConstants.m file... I have: extern int abc[3] = {11, 22, 33};
Can we access the integer type variables in classB which are declared in classA by not using extern? For objects I used ClassA *obj1 = [[ClassA alloc]init]; And accessed the objects of classA into开发
Why does extern int n not compile when n is declared (in a different file) static int n, but works when declared int n?(Both of these declarations were at file scope.)
Why can\'t I compile this code? //main #include \"stdafx.h\" #include \"X.h\" #include \"Y.h\" //#include \"def.h\"
Is there a difference between declaring a static variable outside of a function and declaring a static variable inside a function?
What does the extern keyword mean? I\'ve seen that 开发者_C百科in front of an function declaration like
I\'m attempting to attach to an object that I\'ve previously detached from. My detach operation is as follows:
