#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
