Thread: Need help with this code

So a bit of what I am trying to do. I am trying to make a program that ask you for name and gender (age is always used lets use gender be deferent, and yes I hate doing hello world for the same reason )
and then ask if the information is correct and if it's not to redo it all.

Code:

#include <iostream> 
#include <cstdlib>

using namespace std;

int  main()
{
 string my_name;
 string my_gender;
 string yes_no;

     
     
   cout<<"Welcome please type your name \n";
      cin>> my_name;

      cout<<"Hello "  <<  my_name <<  " and what gender are you?";
      cin>>my_gender;
      cout<< "You are " << my_name << "and are a " << my_gender << "? /n";
      cout<< "type yes or no";
      cin>> yes_no;

After this line I had a few plans to make this work
A. loop if yes_no = no
B. loop while yes_ no = no

Looking at them I think they are the same thing but I could be wrong
and even so is one "bad programing" if so why?
Can strings even work this way? I see no reason why not but the error is making me think other wise, it says "no" is not declared but it should be with cin>> yes_no right?

"Normal text is treated as code by the compiler. If you want any text to be a string literal (that is anonymous string data) you have to surround it in double quotes. For example, this entire post is treated as one string literal by C++, because of the double quotes. You could compare this post with a string."

"Not to mention that your do-while loop is also wrong because you're using assignment instead of an equally comparison (that is ==)."

It works thanks. But why do while acording to your tut on it

DO..WHILE loops are useful for things that want to loop at least once

but how is that defreint fomr while in this case?
as the loop is not decide intill you use the yes_no string do you need one that just make sure it gose though once? or am I missing a bigger pitcure0?

Not if the later somehow depends on the former.

Code:

class HelloWorldApp 
{
     public static void main(String[] args) 
    {
         System.out.println("Hello World!");
     } 
}

is simpler than

Code:

#include<iostream>
int main()
{
    std::cout<<"Hello World !";
    return 0;
}

?

Heh, with a program as trivial and on such a small scale as 'Hello World', there isn't much difference granted. However, when things get more larger in scope and C++ introduces memory management, pointers* etc. than the added complexity becomes quite apparent. Obviously though Java pays for this 'advantage' with less performance.

*Although I guess it could be argued that Java references are watered down C++ pointers...

Generally speaking, if you want to learn any language, you should focus on learning that language. Not try to learn one language first, and then the next language by adapting what you learned with the first. If moving from any language to another, one of the major steps is unlearning techniques from the first language before you can properly use the second language.

For that reason, I generally advise against learning C if you want to learn C++, advise against learning C++ if you want to know C, advice against learning Java as a stepping stone to C++, or advise against learning C++ and then using that knowledge as a basis for learning Java.

That is not suggesting any of the languages are better or worse than the others. But the human mind finds it easier to learn good habits than to unlearn bad habits.

Ah, good points. I think I may be guilty of not wording my original post carefully enough. Someone shouldn't think that by learning Java they are a mere stones throw away from C++. Getting to grips with it takes a lot of knuckling down, and often you'll be going over something that you thought had nailed in Java but now requires a whole new approach or way of thinking.
That being said the general ideas of OOP, control structures etc. and the logic on which they operate are the same. And maybe it's just me but the ease of the syntax made learning and testing these concepts both surprisingly quick and enjoyable.
And Put it this way, even without prior programming experience, most could have a very good grip on Java within a week or two. And that's probably why it's so popular as the language most people cut their teeth on.
