Right now I'm designing a text-base console game. One thing that I need is a Timer. So say you ask the user to solve and enter the solution to this equation: (2 * 3) + 5. But, the user only has 7 seconds to answer it. If he/she gets it in 5 seconds, he/she wins. If it takes more than 7 seconds, he/she looses. What I want to know, is how would you make that happen. Is there a function in C++ that I could use (haven't found or heard of one at this point)? Do I create my own function to make it happen (if so, how? Where would I start)? Anyway, if anyone could provide any insight or ideas, I would appriciate it. Thanks.

on unix, you can use 'time()' if you don't need sub-second precision

on windows, you can use 'timeGetTime()'

The standard clock() function can be used for sub-second precision timing.

If you are using a windows OS then you can use GetTickCount() which increments every millisecond. It is really convienient :)

I think this will help you.

timer.h

#ifndef _TIMER_#define _TIMER_#include <ctime>class Timer {    clock_t counter;public:    Timer(): counter(0) {};    bool elasped(clock_t ms)    {        clock_t tick = std::clock();        if(tick - counter >= ms)        {             counter = tick;             return true;        }        return false;    }};#endif

main.cpp

#include <iostream>#include "timer.h"int main(){    Timer timer;    while(true)    {        if(timer.elasped(1000))            std::cout << "ding!\n";    }}
