The Official Programming Thread

[hash94]

Well, I am taking BS Chem Eng, But went through basic C++ programming.

And the thing is that programming fascinated me a lot, i want to learn more on this,basically self study.

So can someone guide on what should i start learning and where, and could this added skill of programming help in future?

 

[salman09]

so guyz here I just started doing BS CS from NUST
our teacher refferred to different books for C language including
Harvey_Dietel_-_C_How_to_Program_6th_Edition.pdf
Robert_Sebesta_-_Concepts_of_Programming_Languages.pdf
Steve_Oualline_-_Practical_C_Programming_3rd_Edition.pdf
and C for dummies

so guyz need some suggestion which book should I start with and in order to improve my programming skills what should be my pattern of studying
as I am a beginner and starting from the scratch and in the end of semester 1 i wanted to be a pro in C language

Dietel. That's where you need to start from.

Firstly, there are issues with your spaces.

As for making multiple files, what you make in the .h files are interfaces, not definitions. If you remove all the definitions, you'll be left with a clean list of functions from which you can guess what a class does. In your case, it'd be something like.

class shape
{
private:
int a,b;
public:
shape();
float area_r();
float area_t();
void getValues(); //It's better to use a constructor for this

}'

Then you make the defintions in the .CPP file. And you need to use header guards(#ifndef and #def ), especially if you there is more than 1 file. In the .cpp file, you'll define

shape::shape() {\\stuff}

float shape::area_r(){\\definition}

float shape::area_t(){\\definition}

If your code is working in a single file, cut-pasting the definitions to the .cpp file shouldn't be an issue, make sure to include the .h file at the top. You might have to include iostream and using namespace std again as well depending on the situation.

I asked help regarding the logic. I know all that stuff you mentioned

Can anyone solve this question for me?

Create a class called shape using a Header containing only class member functions prototypes (not Definition’s). Store your program in 3 separate files named as Class_Name .h Class definition only function prototypes Class_Name .cpp Class member functions definitions File_Name.cpp Main program for operation
Create a class called shape using a Header containing only class member
functions prototypes (not Definition’s). Store your program in 3 separate files
named as
Class_Name .h  Class definition only function prototypes
Class_Name .cpp  Class member functions definitions
File_Name.cpp  Main program for operation

Your Output should appear as:
Enter your choice (T) for Triangle and (R) for Rectangle and (E) to Exit
T
Enter Value for x 6
Enter Value for y 7
Triangle
Values entered are 6 and 7
Area is 21

Area is 42

E
Exiting

My poor try with loads of errors

cout<< a << b;

}

Creating a header file and defining its function in another file is easy. I need help regarding the logic which is to be made.

are you getting compile time errors or is the output not as you expected it to be?

 

[MegamanEXE]

Dietel. That's where you need to start from.

Dietel is a terrible book to start from Kinda intimidating for someone who has never seen a programming language before.
[MENTION=13101]Hassan[/MENTION] What seems to be the issue then? BTW a switch statement is much better for stuff like menus.

 

[Hassan]

both .

Assalamo Alaikum guys, I've absolutely zero knowledge of programming kindly suggest me which language schould I learn. And also suggest some books. Thanks.

Go with C++. It will help you in the long run.

 

[Newton]

both .

i can make a running example in java

will that help?

I would suggest C++,PYTHON AND JAVA .....Python is good for beginners ...

 

[gow3]

Depends on how much time you're willing to invest. If you have a lot of time, I'd recommend python for a few days and then moving to C++ (Just a preference because I make iOS Applications so I'll assume you want to do the same. Learn C++, learn objective-c, start making apps).

 

[MegamanEXE]

Honestly though, I borrowed a Python book from my uni's library. Even though I had a very good grasp on programming concepts and coding, I felt Python isn't really as beginner-friendly as I thought it'd be. Throwing terms like Frozen Binaries and Interpreters (alongwith others I can't remember ) at amateurs isn't a good plan. I'd still recommend C/C++.

okay.

[EternalBlizzard]

Ruby is beginner friendly..... learn ruby

 

[helraizer]

Ruby is beginner friendly..... learn ruby

better than python?as in beginner friendly.

 

[Gizmo]

Man, don't go for beginner friendly stuff, just get a good book that teaches C++, once you learn that alongwith all the basic programming concepts then you can go for any language you want. There's a reason why most Unis start sutdents off with C++. it's a good place to start.

I started learning C++ just a few months ago and before that I had zero programming experience other than a few programs I made in BASIC for school which I don't even remember anymore. It's not that hard.

i dont know wtf is beginner friendly , seriously i mean seriously C++ is the language i learnt very first as a programmer , and instead of learning it from online tutorials and examples indeed book is best , examples and online sites are just extras for me or bonus content you guys can say , once you complete OOP then you can create mini projects to test the skills later learn any language , maybe later you dont need a book only online courses would be enough but very first time you need proper classes you need a regular teacher you need a good book and time to practice what have you learnt


programming is a very hard thing if you got no passion for it , if you do so it is the the fun , as this field i mean developing things for me is the most enjoyable work for me and i seriously love to code more than se* :laugh1:

 

[Gizmo]

You don't really need a teacher that bad, just a good book + the will to give it some time and practice IMO. :tv:
