    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.

    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.

    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.
