c++时钟程序代码

用c++的话还是弄成类比较好的，下面是我的解决方法：

#include <ctime>

#include <cstring>

class Timer

{

private:

static const int size = 50;

std::time_t time;

std::tm localTime;

char Ascll[size];

char flag;

public:

Timer()

{

std::time(&time);

flag = 0;

}

~Timer() {}

const char printTime()

{

if(!flag)

{

localTime = std::localtime(&time);

std::strcpy(Ascll, std::asctime(&localTime));

}

flag++;

return Ascll;

}

double timeDiff(Timer time2) const

{

return difftime(time, time2 -> time);

}

} ;

int main()

{

Timer t1;

for(int i = 0; i < 10000; i++ )

{

cout << i;

}

Timer t2;

std::cout << t1printTime() << std::endl;

std::cout << t2printTime() << std::endl;

std::cout << t2timeDiff(&t1) << std::endl;

return 0;

}

可以使用C语言标准库中的timeh头文件中的clock()函数来获取程序运行时间。具体的方法如下：

在程序开始运行时，调用clock()函数，获取当前系统时间，并将结果保存在一个变量中，如start_time。

程序执行完毕后，再次调用clock()函数，获取当前系统时间，并将结果保存在另一个变量中，如end_time。

计算程序运行时间，可以通过end_time - start_time来得到程序运行时间的时钟数，再除以CLOCKS_PER_SEC，即每秒钟的时钟数，得到程序运行时间的秒数。

代码示例：

#include <stdioh>

#include <timeh>

int main() {

int n = 16; // 盘子数量

int A = 1, B = 2, C = 3; // 三个柱子的编号

clock_t start_time, end_time;

start_time = clock(); // 记录开始时间

// 执行汉诺塔 *** 作

//

end_time = clock(); // 记录结束时间

double duration = (double)(end_time - start_time) / CLOCKS_PER_SEC; // 计算运行时间

printf("程序运行时间为 %2f 秒\n", duration);

return 0;

}
