Question

我正在使用WinCE7.I需要在t1之类的变量中存储特定输入高的时间值。然后，如果输入再次为高，则将时间值存储在另一个变量t2中。如何在c。

中执行此操作

现在我在t1节省时间，如下所示：

sprintf(time," %d:%d:%d:%d\n",systemTime.wHour,systemTime.wMinute,systemTime.wSecond,systemTime.wMilliseconds);

if(input==high)
{
 strcpy(t1,time);
 printf("time %s\n",t1);
}

Answer 1

你可以使用数组存储多次等。下面是一种伪代码。根据您的实际代码进行更改。

char t1[30][20], time[20];
int counter = 0 , low=0;
    while(counter < 30) {
        sprintf(time," %d:%d:%d:%d\n",systemTime.wHour,systemTime.wMinute,systemTime.wSecond,systemTime.wMilliseconds);

        if(input==high)
        {
         strcpy(t1[counter],time);
         printf("time %s\n",t1[counter]);
        //reset the input or whatever
         input = low;
         counter++; // change index 
        }
    }

Answer 2

使用整数值i = 0计算输入高的次数。例如：

i = 0;
if(input==high)
{
 i++;
 if(i==1)  //Input is high for the first time
 { 
   strcpy(t1,time);
   printf("time %s\n",t1);
 }
 if(i==2)  //Input is high for the second time
 { 
   strcpy(t2,time);
   printf("time %s\n",t2);
 }
 if(i==3)  //Input is high for the third time
 { 
   strcpy(t3,time);
   printf("time %s\n",t3);
 }

 //same for other 
}

在变量中存储时间值并更新它
