Global variable management in C language

In C language, information encapsulation is weaker, only static variable file scope.


If not constrained, it is easy to cause global variables to fly.


If you define a global structure, put the global variables into this globlevariate, you should be good at least a little bit more elegant than the bare Ben.


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


The approximate pseudo-code looks like this.
struct globlevariate
｛
struct ModuleVariate1;
struct ModuleVariate2;

...

｝

It is also forbidden to define variables outside of the function, which can improve the management of global variables.
