#include <iostream> using namespace std; //函数参数声明为引用类型(使用&符号),即可实现引用传递。 void swap(int& a, int& b) { int temp = a; a = b; b = temp; } int main() { int x = 10; int y = 20; cout << "交换之前:" << endl; cout << "x 的值: " << x << en...
using namespace std; 然后编译时出现 error C2871: 'std' : does not exist or is not a namespace 查了一下,原来 C++有两个不同版本号的头文件。引入名字空间这个概念曾经编译器用的是#include <iostream.h>, 而引入名字空间的概念以后std名字空间的头文件名称字变成了<iostream>。 <iostream.h>是比較老...
File names should include both platform name and module functions. For example: A driver file name example ismcu_driver_adc.c. A utility file name example isutility_crc32.c. A HAL file name example ishal_adc.c,hal_adc.h. A app file name example isapp_gateway.c. A board file name e...

本章我们将编写一个2D跑酷类游戏,玩家键盘控制火柴人奔跑和跳跃,躲避蝙蝠到达终点。游戏地图随机生成,随着关卡数的增加,游戏难度越来越大,效果如图所示。 首先定义Player类,实现异步输入控制和延时改进;然后利用枚举类型进行多种状态的切换,实现火柴人的奔跑动画、跳跃控制;接着添加地面类与场景类,实现火柴人与地面的碰...
