第三题

C++
主要考察变量类型的字节知识

1. 人肉记忆，short 2 bytes | int 4 bytes | long 8 bytes | long long 8 bytes.
2. 利用sizeof(date type)输出；
   代码如下：

   #include<iostream>
   using namespace std;  
   int main(){
    cout<<"The size of short is "<< sizeof(short)<<" bytes."<<endl;
    cout<<"The size of int is "<<sizeof(int)<<" bytes."<<endl;
    cout<<"The size of long is "<<sizeof(long)<<" bytes."<<endl;
    cout<<"The size of long long is "<<sizeof(long long)<<" bytes."<<endl;
    return 0;
   }

ps: 这里'<<'符号 'main'打错了，查了半天，要注意; 回头看一下具体的类型知识
