Thread: Variable question I can't find answer to

    Variable question I can't find answer to

    Hello, I am sure this is simple, It must be too late, I am going through tutorials, I simply cannot find how to define a variable that is text?

    is it char?

    char[100] for example?

    I know int is for integer, all examples I see have integer variables, I simply want to do the basic

    "hello, your name is (variable)" where
    (variable) is data from input from user

    I just can't find how to define a text variable

    I know, silly, I can do if/loops with int variables, but I can't find text variables, ok, being laughing

    Ps. It's 5 am, my apologies if I missed this in the faq, it is not to be rude, I really am digging to find this, not asking for code to be written for me (gulp)

    >>> char[100] for example?

    That is one way. In C/C++ there is a category of strings, (text), called "Null terminated strings". These are basically arrays of characters with a NULL character to mark the end of the string. Your array above could hold a text string 99 characters long, (the hundreth character would be the NULL to terminate it).

    #include <stdio.h> 
    int main() 
    	char abc[6]; 
    	return 0;
    There are other types of string as well. What to use depends on what you are doing, with what, why, and with what goal.

    there are two basic ways, one is char[50] or whatever, but if you include the string library you can decalre a string directly:

    #include <iostream>
    #include <string>
    using namespace std;

    int main(void)
    string name = "Herbert";

    cout << "hello " << name ;

    hope this helps.
    if you use the standard namespace you can also do direct comparisons, i think, like;

    if (name == othername)

    without using strcmp etc.

    Thank you so much, this was nice of you (and damn fast)

    I will practice this
