c++：warning: deprecated conversion from string constant to 'char*' [-Wwrite-strings]

首先，它任然是有效的C++代码，应为你写的char* 是具有c风格的字符串，所以g++不识别

可以选择在编译的时候加上：g++ -Wno-write-strings text.cpp //忽略警告。。。

其实这样是并不是很安全

上代码

1 #include <iostream>2 #include <stdio.h>3 #include <string.h>4 using namespace std;5 6 class Student{7   private:8     int score;9     char *name;//可变的变量10   public:11     Student(const char *name,int score);12     Student(Student& stu);13     ~Student();14     void  show();15 };16 17 Student::Student(const char *name1,int score1)//这里改了const18 {19   cout<<"constructing ..."<<endl;20 21   name = new char[strlen(name1)+1];22   if(name != 0)23   {24     strcpy(name,name1);25     score = score1;26   }27 }28 29 Student::~Student()30 {31   cout<<"Destructing..."<<endl;32   name[0] = '\0';33   delete name;34 }35 36 Student::Student(Student& stu)37 {38   cout<<"copy constructing ..."<<endl;39   name = new char[strlen(stu.name)+1];40   if(name != 0)41   {42     strcpy(name,stu.name);43 44     score=stu.score;45   }46 }47 48 void Student::show()49 {50   cout<<name<<endl;51   cout<<score<<endl;52 }53 54 int main()55 {56   Student stu1("huhao",101);//在这里传入的是const的变量57   /*58   Student stu2=stu1;59   stu1.show();60   stu2.show();*/61 }
