I am trying to learn C++ and I am trying to make an app where it has you type in two names and then it says name1 has a crush on name2. But my code isn't working right. Can you guys take a look at it and help me out?

Code:

#include 

using namespace std;

int main()
{
    int name1;
    int name2;
    
    cout<<"Type a name: ";
    cin>> name1;
    cout<<"Type another name: ";
    cin>> name2;
    cout<<"Guess what?" << name1 <<"has a crush on "<< name2 <<"\n";
    return 0;
}

you need a cin.get(); or cin.ignore(); i think

I had those in, but it didn't make a difference. What do those do any way, I just copied code from a tutorial site and messed around with it.

EDIT: I added in the cin.ignore(); codes and the cin.get(); too. It will compile with and with out them, but when I go to use the program it just displays this:

Code:

Last login: Thu Aug 30 14:46:33 on ttyp1
Welcome to Darwin!
172:~ jeff$ /Users/jeff/Desktop/programs/enter/enter1; exit
Type a name: jeff
Type another name: Guess what?-1880832560has a crush on -1073743208
logout
[Process completed]

I am opening this through Terminal (on OS X) and compiling it in the same app.

Here is the source now:

Code:

#include 

using namespace std;

int main()
{
    int name1;
    int name2;
    
    cout<<"Type a name: ";
    cin>> name1;
    cin.ignore();
    cout<<"Type another name: ";
    cin>> name2;
    cin.ignore();
    cout<<"Guess what?" << name1 <<"has a crush on "<< name2 <<"\n";
    cin.get();
    return 0;
}

This is what I for when I tried to compile it.

Here is my source code now:

Code:

#include 

using namespace std;

int main()
{
    int 1;
    int 2;
    
    cout<<"Type a name: ";
    cin>> 1;
    cin.ignore();
    cout<<"Type another name: ";
    cin>> 2;
    cin.ignore();
    cout<<"Guess what?" << 1 <<"has a crush on "<< 2 <<"\n";
    cin.get();
    return 0;
}

Are my arrows pointing the right way in the

Code:

cout<<"Guess what?" << 1 <<"has a crush on "<< 2 <<"\n";

line?

think i figured it out- you need a char because you cant store letters in variables

pspkillsds · #8 (**permalink**) 08-31-2007, 11:25 AM

I know my reply helped alot.

dq9 · #9 (**permalink**) 08-31-2007, 01:41 PM

Indeed it did pspkillsds.

iamstrange14: What is a char? Don't forget, I am still learning and don't know to much yet. And thanks for all of your help so far.

EDIT: my girlfriend came to the rescue. Here is my new code (that works):

Code:

#include 
#include 

using namespace std;

int main()
{
    string name1;
    string name2;
    
    cout<<"Type a name: ";
    cin>>name1;
    cin.ignore();
    cout<<"Type another name: ";
    cin>> name2;
    cin.ignore();
    cout<<"Guess what? " << name1 <<" has a crush on "<< name2 <<"\n";
    cin.get();
    return 0;
}

iamstrange14 · #10 (**permalink**) 08-31-2007, 06:52 PM

so it looks like you left out an include and hads the .get's and .ignore's mixed up? i dont know too much either and i was still learning until i screwed up dev c++
