对于在.h里面的强符号,应该始终秉持这样一种观点:尽可能将header files封锁在include他的单个.c文件。除非对那些必须要共享的variable or function,其余强符号最好加上static。虽然header guard帮我们避免了一份头文件多次包含的情况,确保整个头文件在最终可执行文件中只有一份。但是header guard无法保证header files中的...
intmain{ // you don't need to capture a global variable [] {returnx; }; } 但如果是局部变量,由于它的存储时期为 automatic,就必须捕获才能使用: intmain{ intx =42; // you have to capture a local variable [&x] {returnx; }; } 但如果使用 static 修饰该局部变量,就无需再进行捕获: int...
so the effect of having a static variable in a header file and including that in any file would be as if you have declared the static variable in the file in which you included the header, and it's scope would be limited to that file only... i.e. you cannot "extern" the same va...
This line serves two purposes: it instantiates the static member variable (just like a global variable), and initializes it. In this case, we’re providing the initialization value1. If no initializer is provided, static member variables are zero-initialized by default. Note that this static m...

If I have a global variable that is defined as static bool MyLabel;, how would I add it to a header so that it can be accessed by multiple files? Normally I would use the extern keyword in the header, but that doesn't work in combination with static as it gives the following ...
