楼主你的代码逻辑太混乱了，我猜测你是想做个定时器吧，别用Sleep()延时900多毫秒，会阻塞进程，按键得不到及时相应。我改进一下代码，如下所示：#include <iostream.h>
#include <windows.h>
#include <time.h>
#include <stdio.h>
#include <iomanip.h>
#include <conio.h>
int h, m, s;
void refresh();
void add();
int main()
{
char key;
bool bStart = false;
h = m = s = 0;
refresh();
while(1)
{
if(kbhit())
{
key = getch();
if(key == ' ') bStart = !bStart;
else if(key == 'c')
{
h = m = s = 0; //C键归零
refresh();
}
}
if(bStart) add();
}
return 0;
}
void refresh()
{
system("cls"); //clear screen
cout<<" "<<setw(2)<<h<<" : "<<setw(2)<<m<<" : "<<setw(3)<<s<<endl; //show time
}
void add() //实现计时累加
{
static DWORD clk = GetTickCount();
if(GetTickCount() - clk > 1000)
{
clk = GetTickCount();
s++;
if(s>=60)
{
s=0;
m++;
}
if(m>=60)
{
m=0;
h++;
}
refresh();
}
else Sleep(1);
}
