题解

#include <iostream>//经典头文件走一个
using namespace std;//命名空间走一个
int main(){//必不可少
    int hu=2200,chang=4396;//先int定义两个变量并赋值输出
    cout <<chang <<"+" <<hu <<"=" <<chang+hu <<endl;//输出，endl表示换行
    cout <<chang <<"-" <<hu <<"=" <<chang-hu <<endl;
    cout <<chang <<"*" <<hu <<"=" <<chang*hu <<endl;
    cout <<chang <<"/" <<hu <<"=" <<chang/hu <<endl;
    cout <<chang <<"%" <<hu <<"=" <<chang%hu;
    return 0 ;//return 0结束
    }
