编写计时程序的方法取决于你使用的编程语言。以下是几种常见编程语言的计时程序示例:

C语言

```c

include

include

int main() {

clock_t start_time, end_time;

double total_time;

// 开始计时

start_time = clock();

// 运行需要计时的代码块

// ...

// 结束计时

end_time = clock();

// 计算总时间

total_time = (double)(end_time - start_time) / CLOCKS_PER_SEC;

printf("Total time: %f seconds\n", total_time);

return 0;

}

```

C++

```cpp

include

include

int main() {

auto start_time = std::chrono::high_resolution_clock::now();

// 运行需要计时的代码块

// ...

auto end_time = std::chrono::high_resolution_clock::now();

std::chrono::duration elapsed_time = end_time - start_time;

std::cout << "Total time: " << elapsed_time.count() << " seconds" << std::endl;

return 0;

}

```

Python

```python

import time

start_time = time.time()

运行需要计时的代码块

...

end_time = time.time()

total_time = end_time - start_time

print("Total time: ", total_time, " seconds")

```

Java

```java

public class TimerExample {

public static void main(String[] args) {

long startTime = System.currentTimeMillis();

// 运行需要计时的代码块

// ...

long endTime = System.currentTimeMillis();

long executionTime = endTime - startTime;

System.out.println("程序执行时间: " + executionTime + " milliseconds");

}

}

```

JavaScript (Node.js)

```javascript

const start = Date.now();

// 运行需要计时的代码块

// ...

const end = Date.now();

const totalTime = end - start;

console.log("Total time: " + totalTime + " milliseconds");

```

HTML + JavaScript (浏览器环境)
