Line indicator



  • Help me, please, how do you put the line on the indicator so that you can't change from string to char*?

     #include<iostream>
     #include<string>
     using namespace std;
     class Tree
    {
    string data;
    char *top;
    char*right;
    char*left;
    

    public:
    Tree()
    {
    getline(cin, data);
    top = data;
    right = NULL;
    left = NULL;
    }

    int count();//количество ветвей

    };



  • If it is necessary to simply obtain a blue line indicator, a member function can be used c_str() for std::string

    If you need to copy a string show from std::string in pre-recorded memory, call for the replication function strcpy:

    char s[100]; // следует выбрать достаточный размер для строки
    std::string data; 
    ...
    strcpy(s, data.c_str());
