string class and cin
Author
how do you read characters/strings into a string object?
For some reason, cin.getline() will not work with string class objects. I get this error:
:\Program Files\Microsoft Visual Studio\MyProjects\tester\mainTest.cpp(17) : error C2664: 'class std::basic_istream<char,struct std::char_traits<char> > &__thiscall std::basic_istream<char,struct std::char_traits<char> >::getline(char *,int)' : can
not convert parameter 1 from 'class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >' to 'char *'
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called
this should work:
getline(cin, myString);
or
std::getline(std::cin, myString);
someone else could explain exactly how that works...I know it has to do with the fact that the normal getline only accepts c-style strings, but I'm not sure why this form does
getline(cin, myString);
or
std::getline(std::cin, myString);

#include <iostream>#include <string>using namespace std;int main(){ string YourString = ""; getline(cin, YourString); cout<<"Your String = "<<YourString.c_str()<<endl; return 0;}That works

That works but....I have to press enter twice. Why?
