How to pause the execution of a C language program

In C language programming, you can pause the execution of the program by using the following function:

• sleep()

sleep() The function will pause the program for the specified number of seconds. Its prototype is:

#include <unistd.h>
unsigned int sleep(unsigned int seconds);

where, The seconds parameter specifies the number of seconds to pause. After the function call is successful, the program will pause execution and wait for the specified time.

Steps to pause the program:

1. Include the necessary header files in the header file: <unistd.h></unistd.h>
2. Use the sleep() function to pause program execution.
3. Specify the number of seconds to pause as a parameter.

Example:

#include <stdio.h>
#include <unistd.h>

int main() {
    printf("这个程序将会暂停 5 秒。\n");
    sleep(5);
    printf("程序已恢复执行。\n");

    return 0;
}

Output:

<code>这个程序将会暂停 5 秒。
(5 秒暂停)
程序已恢复执行。</code>
