    mad libs

    Im writing my first real C++ program I previously knew C but I want to switch to C++... well I wanted to write a mad libs program, but the problem is I used char as my data type for all the words, but Char is only 1 digit, so what would I use for a string data type?

    Use the class 'String', or use an array of characters, or a pointer to a character and allocate memory for them.

    Hope is the first step on the road to disappointment.

    In both C and C++, a char is one character. A string can be stored in a character array.

    char Name[20] ; // Can hold a a 19 character string plus the null termination.

    C-style strings still work in C++.

    You shouldn't get into the habit of using c-style's in C++, imo.

    Heres an example code using strings:

    Code:
    #include <iostream.h>
    #include <string.h>
    
    
    int main(int argc, char* argv[])
    {
    	string users_name;
    
    	cout<< "Enter your name: ";
    	cin>>users_name;
    
    	cout<< "Hello " << users_name << endl;
    
    	return 0;
    }

    True, and you shouldn't get into habit of using old headers.
    <iostream>, <string> and the usual std:: stuff.

    Are you sure? I have 6 and it compiles fine...
    You only run into problems which you mix and match old-style with new-style.

    Is there a reason no one has offered up :
    PHP Code:
    char *pString;
    pString "What ever.";
    // or
    cin>>pString;
    // want to access individual letter
    cout << "letter: " << pString[2] << endl
    This seems really really flexible to me, And I'm a little concerned I haven't seen it pop up yet. Is there something I'm missing, something wrong with this method?
    c++->visualc++->directx->opengl->c++;
    (it should be realized my posts are all in a light hearted manner. And should not be taken offense to.)

    That is only acceptable if you never wish to edit the string. When you just make a pointer to a string that you just defined with "string goes here", the string itself is placed in unwritable memory. If you ever try to edit anything in the string, you should in most cases get a big fat runtime error.

    Oh ok. I guess that clears it up for me.
    I can write a simple edit() function that can cover for the lad of character editing.

    Thanks for the clarification.

    Managing character arrays is a very tedious task and was a priority and nuisance for C coders. The C++ standard's string class is powerful, flexible, and robust, I recommend it's use for any serious string usage.

    Why doesnt this compile for me?

    #include <iostream>
    #include <cstring>
    using namespace std;
    int main()
    {
    string Hello;
    Hello = "Hello";
    cout<<Hello;
    return 0;
    }

    It doesnt see string as a data type. I am using Visual C++ 6.

    Code:
    #include <iostream>
    #include <string>
    using namespace std;
    /* ... */
    <cstring> is the C-header with C string functions like strlen(). <string> is the C++ header with the string class.
