初始化模块,很好的一种写法.

#include <iostream>
#include <sstream>


enum MODULEID {
	MODULE_A,   
	MODULE_B,
	MODULE_C ,
	MODULE_D,
	MODULE_E,
	MODULE_F,
	MODULE_NONE
};

void Init()
{
	MODULEID eModuleId = MODULE_A;
	bool bStart = true;
	while(bStart)
	{
		switch(eModuleId)
		{
		case MODULE_A:
			std::cout<<"MODULE A is ok"<<std::endl;
			eModuleId = MODULE_B;
			continue;
		case MODULE_B:
			std::cout<<"MODULE B is ok"<<std::endl;
			eModuleId = MODULE_C;
			continue;
		case MODULE_C:
			std::cout<<"MODULE C is ok"<<std::endl;
			eModuleId = MODULE_D;
			continue;
		case MODULE_D:
			std::cout<<"MODULE D is ok"<<std::endl;
			eModuleId = MODULE_E;
			continue;
		case MODULE_E:
			std::cout<<"MODULE E is ok"<<std::endl;
			eModuleId = MODULE_F;
			continue;
		case MODULE_F:
			std::cout<<"MODULE F is ok"<<std::endl;
			eModuleId = MODULE_NONE;
			continue;
		default:
			std::cout<<"MODULE is fully completed"<<std::endl;
			bStart = false;
		}
	}

}

int main()
{
	Init();

	return 0;
}

result:
MODULE A is ok
MODULE B is ok
MODULE C is ok
MODULE D is ok
MODULE E is ok
MODULE F is ok
MODULE is fully completed
