System Pause Command

The system(“pause”) command in C++ is used to pause the execution of a program until the user presses any key. This command is specific to Windows systems and is not portable to other operating systems like Linux or macOS.

#include <stdio.h>
#include <stdlib.h>
 
int main()
{
    // 数组指针是一个**指针**，它指向的是一个数组。
    int a[5] = {1, 2, 3, 4, 5};
    int (*p)[5] = &a; // 定义一个数组指针，指向一个包含5个int类型元素的数组
    // & 把数组当成一个整体
 
    for (int i = 0; i < 5; i++)
    {
        printf("Value of a[%d] = %d\n", i, (*p)[i]); // 通过数组指针访问数组元素的值
        printf("Value of a[%d] = %d\n", i, *(*p + i)); 
    }
    system("pause");
    return 0;
}

这样运行编译后的exe程序，可以暂停程序执行，直到用户按下任意键。
