Simpelt spørgsmål - hurtige points

#include "stdafx.h"
#include <iostream>
#include <string>
#include <stdlib.h>
using namespace std;

int main()
{
    string name;
    int age;

    cout << "Variables, input, and output\n\nPlease enter your first name and press \<ENTER\>.\nName: ";
    cin >> name;

    cout << "\nPlease enter your age and press \<ENTER\>.\nAge: ";
    cin >> age;

    cout << "\nHello " << name << "!\nYou are " << age << " years old!\r\n";

    system("PAUSE");
}

Er nok den nemmeste måde at gøre det på.

Ok... Tester det lige...

Hehee...!
Så virker det... Kan man vel godt sige, men...
Jeg vil jo bare holde vinduet obent; ikke have in tekst frem om at trykke en tast for at lukke... Kan jeg ikke bare få vinduet til at blive åbent, så jeg selv kan skrive en tekst og brugeren derefter kan lukke vinduet ned - UDEN den indbyggede meddelelse?

Problemet er at der hænger et linieskift i keyboard bufferen, og de er ualmindeligt svære at få ud.

Man kunne løse det med:
#include "stdafx.h"
#include <iostream>
#include <sstream>
#include <string>
#include <stdlib.h>
using namespace std;

template <typename T>
bool Get(T &t, istream &is = cin)
{
  string s;
  getline(is, s);
  stringstream ss(s);
  return ss >> t;
}
int main()
{
    string name;
    int age;

    cout << "Variables, input, and output\n\nPlease enter your first name and press <ENTER>.\nName: ";
    getline(cin, name);

    cout << "\nPlease enter your age and press <ENTER>.\nAge: ";
    Get(age);

    cout << "\nHello " << name << "!\nYou are " << age << " years old!\r\n";
    cin.get();
}

Bemærk at jeg bruger getline til navn, så kan der også være mellemrum.
Man skal ikke have \ foran <> i "string literals"

Det fik jeg ikke helt fat i...
Men hvorfor dur dette ikke?:

#include "stdafx.h"
#include <iostream>
#include <sstream>
#include <string>
#include <stdlib.h>
using namespace std;

    template <typename T>
bool Get(T &t, istream &is = cin) {
    string s;
    getline(is, s);
    stringstream ss(s);
    return ss >> t;
}
int main() {
    string name;
    int rating;
    string comment;

    cout << "Closing window\n\nHow would you rate C++ from 1 to 5?\nPlease type your ansver and press \<ENTER\>.\nRating: ";
    Get(cin, rating);

    cout << "\n\nPlease enter a comment and press \<ENTER\>.\nComment: \n\n";
    getline(comment);

    if(rating < 0) {
        cout << "Whoa! You really don't like C++...\nYou rated it " << rating << "!\nYou also wrote:\n" << comment << "\nInteresting...";
    } else if(rating == 0) {
        cout << "I see you really don't like C++...\nYou rated it " << rating << "!\nYou also wrote:\n" << comment << "\nInteresting...";
    } else if(rating == 1) {
        cout << "I see you  don't like C++...\nYou rated it " << rating << ".\nYou also wrote:\n" << comment << "\nHmm...";
    } else if(rating > 1 && rating < 5) {
        cout << "Ok...\nYou rated it " << rating << "...\nYou also wrote:\n" << comment << "\nPretty normal...";
    } else if(rating == 5) {
        cout << "I see you like C++...\nYou rated it " << rating << "!\nYou also wrote:\n" << comment << "\nI like C++ too!";
    } else if(rating > 5) {
        cout << "I see you really like C++!\nYou rated it " << rating << "!\nYou also wrote:\n" << comment << "\nI like C++ too!";
    } else {
        cout << "There must be some mistake...\nYou rated it " << rating << "!\You also wrote:\n" << comment << "\nWierd...";
    }
    cout "\n\nPress \<ENTER\> to close this window.";
    cin.get();
}

Get(rating, cin);
Eller blot:
    Get(rating)

Og:
    getline(cin, comment);

(det er måske ulogisk, du kan bytte argumenterne til Get)

Og
    cout << "\n\nPress \<ENTER\> to close this window.";

Og du skal ikke have \ foran < og >

Har ik tid lige nu... Tjekker det i morgen.

Hm!
Jeg forstår ingenting...
Hvorfor dur dette ikke?!:

#include "stdafx.h"
#include <iostream>
#include <sstream>
#include <string>
#include <stdlib.h>
using namespace std;

    template <typename T>
bool Get(T &t, istream &is = cin) {
    string s;
    getline(is, s);
    stringstream ss(s);
    return ss >> t;
}
int main() {
    string name;
    int rating;
    string comment;

    cout << "Closing window\n\nHow would you rate C++ from 1 to 5?\nPlease type your ansver and press <ENTER>.\nRating: ";
    Get(rating);

    cout << "\n\nPlease enter a comment and press <ENTER>.\nComment: \n\n";
    getline(cin, comment);

    if(rating < 0) {
        cout << "Whoa! You really don't like C++...\nYou rated it " << rating << "!\nYou also wrote:\n" << comment << "\nInteresting...";
    } else if(rating == 0) {
        cout << "I see you really don't like C++...\nYou rated it " << rating << "!\nYou also wrote:\n" << comment << "\nInteresting...";
    } else if(rating == 1) {
        cout << "I see you  don't like C++...\nYou rated it " << rating << ".\nYou also wrote:\n" << comment << "\nHmm...";
    } else if(rating > 1 && rating < 5) {
        cout << "Ok...\nYou rated it " << rating << "...\nYou also wrote:\n" << comment << "\nPretty normal...";
    } else if(rating == 5) {
        cout << "I see you like C++...\nYou rated it " << rating << "!\nYou also wrote:\n" << comment << "\nI like C++ too!";
    } else if(rating > 5) {
        cout << "I see you really like C++!\nYou rated it " << rating << "!\nYou also wrote:\n" << comment << "\nI like C++ too!";
    } else {
        cout << "There must be some mistake...\nYou rated it " << rating << "!\You also wrote:\n" << comment << "\nWierd...";
    }
    cout "\n\nPress <ENTER> to close this window.";
    cin.get();
}

Hov, et sted står der \ hvor der skulle stå \n... Sorry!

Der mangler en << i denne linie: 
  cout "\n\nPress <ENTER> to close this window.";

Ååh... Tester det lige...

Så dur det!
Kode:

#include "stdafx.h"
#include <iostream>
#include <sstream>
#include <string>
#include <stdlib.h>
using namespace std;

    template <typename T>
bool Get(T &t, istream &is = cin) {
    string s;
    getline(is, s);
    stringstream ss(s);
    return ss >> t;
}
int main() {
    string name;
    int rating;
    string comment;

    cout << "Closing window\n\nHow would you rate C++ from 1 to 5?\nPlease type your rating and press <ENTER>.\nRating: ";
    Get(rating);

    cout << "\n\nPlease enter a comment and press <ENTER>.\nComment: \n";
    getline(cin, comment);

    if(rating < 0) {
        cout << "\nWhoa! You really don't like C++...\nYou rated it " << rating << "!\nYou also wrote:\n" << comment << "\nInteresting...";
    } else if(rating == 0) {
        cout << "\nI see you really don't like C++...\nYou rated it " << rating << "!\nYou also wrote:\n" << comment << "\nInteresting...";
    } else if(rating == 1) {
        cout << "\nI see you  don't like C++...\nYou rated it " << rating << ".\nYou also wrote:\n" << comment << "\nHmm...";
    } else if(rating > 1 && rating < 5) {
        cout << "\nOk...\nYou rated it " << rating << "...\nYou also wrote:\n" << comment << "\nPretty normal...";
    } else if(rating == 5) {
        cout << "\nI see you like C++...\nYou rated it " << rating << "!\nYou also wrote:\n" << comment << "\nI like C++ too!";
    } else if(rating > 5) {
        cout << "\nI see you really like C++!\nYou rated it " << rating << "!\nYou also wrote:\n" << comment << "\nI like C++ too!";
    } else {
        cout << "There must be some mistake...\nYou rated it " << rating << "!\nYou also wrote:\n" << comment << "\nWierd...";
    }
    cout << "\n\nPress <ENTER> to close this window.";
    cin.get();
}

Tak for hjælpen begge to!
Jeg kunne bruge begge dele, men pointene går til bertelbrander!
Bare smid et svar...

Jeg samler ikke på point.

Fair nok... Tak for hjælpen!

--- LUKKET ---

Oh...
Undskyld, mathiash!
Det gik lige LIDT for stærkt, med at lukke dette spørgsmål!

Gør skam ikke noget, det var bertel's svar der var din løsning ;)

Tak for det...
Jeg hader at lave fejl :S
