Can anyone explain what this code does?

Con(const char* n){
    char_number = new char[sizeof(n)   1];
    string(n).copy(char_number, sizeof(n)   1);
}

I don't understand the string(n) part. What exactly does this do?

CodePudding user response：

From the documentation:

std::string::string

copy constructor
Constructs a copy of str.
string (const string& str);

from c-string
Copies the null-terminated character sequence (C-string) pointed by s.
string (const char* s);

Note: .copy() is explained here.
