Odd coding problems....

I am currently using Dev-C++ 4. But I am getting some odd coding errors when using cout and cin, here is a example

Code:

---

#include <iostream.h>
#include <stdlib.h>

int main()
{
      int name;
      cout<<"What is your name?";
      cin>>name;
      cout<<"Welcome to Underair" <<name;
      cout<<"How old are you" <<name;
      system("PAUSE");
      return 0;
}

---

When I execute it, where the inputs should be the only thing that shows up is "575" everytime. Can anyone help me with this???

try

Code:

---

#include <iostream.h>
#include <stdlib.h>
#include <string>

int main()
{
      string name;
      cout<<"What is your name?";
      cin>>name;
      cout<<"Welcome to Underair" <<name;
      int age;
      cout<<"How old are you";
      cin >> age;
      system("PAUSE");
      return 0;
}

the datatype you are specifying for name is int
int means integer, which is number
your looking for char...

try this:

Code:

---

#include <iostream.h>
#include <stdlib.h>

int main()
{
      char name[256];
      cout<<"What is your name?";
      cin.getline(name,256,'\n');
      cout<<"Welcome to Underair" <<name;
      cout<<"How old are you" <<name;
      system("PAUSE");
      return 0;
}

The string name thing...In RoD's post, i've never seen that before, but hey, i'll take that.
I've just always used a character array for names and such.
Have fun!

I am a little confused by your question. But are you entering a name such as John or are you entering it in numbers. An int can only hold numbers, and name is declared as an int.

edit: beat.

I forgot about that...havn't coded in c++ in a long time...but can someone tell me how the char thing works?

char object[100];

this reserves memory for 100 chars, which is done using an array. you call each slot in the array such as object[0], object[1], etc. an array of 256 chars isn't really necessary for a name, kindof a high number. hope this helps.

i used a string in my fix.

Okay, I think I get it so its like this

Code:

---

#include <iostream.h>
#include <stdlib.h>

int main()
{
      int age;
      char name[50];
      cout<<"What is your name?";
      cin.getline(name,256,'\n');
      cout<<"Welcome to Underair" <<name;
      cout<<"How old are you" <<name;
      cin>>age;
      cout<<"So you are" <<age;
      system("PAUSE");
      return 0;
}

And the maximum letters they can have in their name is 50?

Yup, you got it, and since about 3 months ago, i've preferred cin.getline over cin>>. I dont know why, but i've been told cin.getline is better.

waaaaaiiiiiit.

Code:

---

name[50];
cin.getline(name,50,'\n');
// the second thing in cin.getline is always the same as your array.
