Question

cout << "Enter your full name";
char* name ;

cin >> name;
  if( _mkdir("c:\\names") == 0 ) {
     cout << "directory successfully created";
  }  else {
       cout << "there was a problem creating a directory";
     }

Now i want to create a file ( a .txt file ) in the directory names with the same name as the name of the user. I mean the name which the user entered during cin >> name;.

How can i do this ?

ofstream writeName( "c:/names/????); —-> PROBLEM

Answer 1

Use std::string instead of char*. As it is your code has Undefined Behavior. Use std::getline instead of >>. With >> only the first whitespace-separated “word” is input. Then, compose the full path in a std::string. The standard string class supports concatenation, so this should be easy.

Say, if that string is path,

std::ofstream f( path.c_str() );
