Timer 에 대해 찾아보다.. 괜찮은 클래스가 있어 구현해봤다.

start 함수로 Timer 를 시작하여 stop 함수전까지 시간을 측정한다.

그리고 getTime 함수로 결과 시간을 얻을 수 있다.

MyTimer.h

#include <time.h>   class MyTimer { public:         MyTimer();         ~MyTimer();           void           start();         void           stop();         void           reset();         bool           isRunning();         unsigned long  getTime();         bool           isOver(unsigned long seconds); private:         bool           resetted;         bool           running;         unsigned long  beg;         unsigned long  end; };

MyTimer.cpp

#include "MyTimer.h"    MyTimer::MyTimer() {         resetted = true;         running = false;         beg = 0;         end = 0; }    MyTimer::~MyTimer() { }   void MyTimer::start() {         if (!running) {                if (resetted)                        beg = (unsigned long)clock();                else                        beg -= end - (unsigned long)clock();                running = true;                resetted = false;         } }    void MyTimer::stop() {         if (running) {                end = (unsigned long)clock();                running = false;         } }    void MyTimer::reset() {         bool wereRunning = running;         if (wereRunning)                stop();         resetted = true;         beg = 0;         end = 0;         if (wereRunning)                start(); }    bool MyTimer::isRunning() {         return running; }    unsigned long MyTimer::getTime() {         if (running)                return ((unsigned long)clock() - beg) / CLOCKS_PER_SEC;         else                return end - beg; }    bool MyTimer::isOver(unsigned long seconds) {         return seconds >= getTime(); }

app.cpp

void main() {         bool quit = false;         char choice;         MyTimer t;         while (!quit) {                cout << " s   start/stop " << endl;                cout << " r   reset" << endl;                cout << " v   view time" << endl;                cout << " q   quit" << endl;                cout << endl;                choice = getch();                switch (choice) {                case 's':                        if (t.isRunning()) {                               t.stop();                               cout << "stopped" << endl;                        }                        else {                               t.start();                               cout << "started" << endl;                        }                        break;                case 'r':                        t.reset();                        cout << "resetted" << endl;                        break;                case 'v':                        cout << "time = " << t.getTime() << " ms" << endl;                        break;                case 'q':                        quit = true;                        break;                }                cout << "------------------------------" << endl;         } }
