guys im having data types problem on strings


What problem?

char Kod
int kod
string Kod[6]
char kod[6]

This is a really bad idea. Use different names for different things.


string Kod[6],f_name[30]; //error point on here
This is an array of six strings, and an array of thirty strings. Did you mean to make thirty strings?

I think you're mixing up string and char arrays. Don't do that.

guys im having data types problem on strings

If you are getting errors it would be helpful to post the errors you receive.

You are including <string.h>, a C library header. There is no C++ string class in the header, only functions to deal with C char arrays.

Including <iostream.h> shows your compiler and/or your class instructions are outdated.

C++ headers don't include .h in the name. It is <iostream>. For C++ strings it is <string>.

Stop using char. char is for holding ONE character. ONE.

Let's count.
Kod='001';
How many characters in '001'? Three.
So can we store THREE characters in one char? No.

Stop using char. Use string.

Stop using char. Use string.

Kod='001';
This should be Kod="001";.

You've been on this problem for ages. Maybe you should try something easier.

#include <string.h>
No no NO. That's for C code. You're trying to write in C++, aren't you?

From here, it just looks like you're really mixed up and you really don't know what you're doing and don't understand basic types like char and int. You need to start again with the simple basics.

What is your compiler/integrated development environment (IDE)?

You may be using one that is outdated.

There are several good FREE compilers/IDEs available that are C++14/17 capable.

Microsoft Visual Studio 2017 Community (Windows) or Code::Blocks (Windows, Mac and Linux).

VS 2017 has a very good debugger integrated into the IDE. Knowing how to debug a misbehaving program is a very essential part of learning to program.

You'll have a much easier time if you carefully organize your list and hierarchy. I see you want to do a linked list, so I propose an OrderManager that deals with the placing and displaying of Orders. Nodes hold orders and point to next. Please also use descriptive variable names -- "F_name" sounds much worse than "food".

Example code (hopefully I didn't leak memory):

Hello helena97,

Sorry I did not find this until this morning and by accident at that.

This is the same program you posted in http://www.cplusplus.com/forum/beginner/233642/3/ It is better to stick with one topic. It makes everything easier to follow.

Still have the same questions. Why did the last project fail. What was wrong and what are the program instructions / requirements?

Knowing what the program should do will better help me help you.

Andy
