Global variable management in C language

In C language, information encapsulation is weaker, only the file scope of static variables.

Assumptions are not constrained. Very easy causes global variables to fly.


Assume that you define a global structure body. Put the global variables in this globlevariate, should be good tube, at least more elegant than the bare.


Further, each module defines its own structure. Put the module public variables in the structure. It would be more elegant to split the globlevariate into multiple small structures.

The approximate pseudo-code is the following way.

struct globlevariate
｛
struct ModuleVariate1;
struct ModuleVariate2.

...

｝

At the same time, it is forbidden to define variables outside the function, which can improve the management of global variables.
