Accelerated C ++ learning notes and solutions-chapter 0

Accelerated C ++ learning notes and solutions-chapter 0

I have mentioned a lot about C ++ before, and this book is also an entry-level book. Therefore, I plan to repeat it. <字符,控制流等部分不会详细介绍,主要记录下题解就ok了.< p>

So, starting from chapter 0.

Chapter 0 describes annotations, # include commands, main functions and functions, and escape characters of input return statements.

Below are some questions:

0-2

#include 
 
  using namespace std;int main() {cout << "This (\") is a quote, and this (\\) is a backslash."<< std::endl;return 0;}
 

0-4

#include 
 
  int main() {std::cout <<"// a small C++ program\n""#include 
  
   \n""\n""int main()\n""{\n""\tstd::cout << \"Hello, world!\" << std::endl;\n""\treturn 0;\n""}" <
   
    

    
0-9
    

    
int main(){}
    

    
0-10
    

    
#include
     
      intmain(){std::cout<<"Hello,world!"<
