2024新版 黑马程序员《C++零基础入门》笔记——第一章03 符号常量
1.符号常量
2.代码文件
方式1:引入windows.h库
# include "iostream"
# include "windows.h"
using namespace std;
# define FAT_BMI 28
# define J2C_RATE 4.19
int main()
{
SetConsoleOutputCP(CP_UTF8);
cout << FAT_BMI << endl;
cout << "焦耳转卡路里需要除以:" << J2C_RATE << endl;
return 0;
}
方式2:system(“chcp 65001”);
# include "iostream"
using namespace std;
# define FAT_BMI 28
# define J2C_RATE 4.19
int main()
{
system("chcp 65001");
cout << FAT_BMI << endl;
cout << "焦耳转卡路里需要除以:" << J2C_RATE << endl;
return 0;
}
3.总结
4.练习作业
// Created by 黑马程序员.
#include "iostream"
#include "windows.h"
using namespace std;
#define NAME "周杰轮"
#define AGE 21
#define HEIGHT 180.5
#define WEIGHT 56
int main()
{
SetConsoleOutputCP(CP_UTF8); // 修改字符编码,解决中文乱码
cout << "我是" << NAME << ",今年" << AGE << "岁。" << endl;
cout << "身高" << HEIGHT << "cm,体重" << WEIGHT << "KG。" << endl;
return 0;
}
