}
0-1: 3+4； 是一個表達式語句，會執行3+4,結果7将放在一個臨時變量裡. 這個表達式沒什麼意義~~.
0-2:
#include<iostream>
int main(){
std::cout << "This (*) is aquote, and this (//) is abackslash." << std::endl;
return 0;
}
ps: /" = " , /' = ' , // = / ;
0-3:
#include<iostream>
int main(){
std::cout << "********" << std::endl;
std::cout << "/ta" <<std::endl;
return 0;
}
/t 占8個字元寬
0-4:
#include <iostream>
using namespace std;
int main()
{
cout<< "#include<iostream>" << endl;
cout<< "int main()" << endl;
cout<< "{" << endl;
cout<< " cout <<\"hello, world!\" << endl;" << endl;
cout<< " return 0;" <<endl;
cout<< "}" << endl;
return0;
}
0-5: 不正确 少了 {} 和 return .
0-6;VC6下能運作 抱一個警告.
0-7; 不正确 /* 注釋牽套了. 導緻一部注釋沒被包含.
0-8;正确 //後的是以内容都被注釋掉了
