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
