Qbasic On Windows Xp

Please people i want to know how u can run qbasic on windows Xp and i created a calculator but i didnt get it all well so it can't add plz can any one help with  the command codes?


cheers

WOW,  Qbasic in the year 2008?? WOW !!!!

you must be proud of this calculator eh 
We used Qbasic in 1998 . . .

this brother will be using vBasic in 2018.

what do you mean by that?? Don't they do QBASIC programming in the Universities?? Infact some universities still do GWBasic till today.

You have got to be joking with that ,  LMAOO!!!! good things start from humble beginnings?? OK ,  dude,  please don't do that ever again!!! LMAO!!!! QBASIC is OBSOLETE. Learning QBASIC when you can NEVER get a job with it is STUPIDITY. I am sorry but that is fact. Even childing in grade schools all over start with current languages not OBSOLETE languages which are no where close to or offer what current languages offer. VB is already in it's 9th version and you feel learning Qbasic whichs is about 2 versions before actual VB is wise??

Actually its true that QBaic is quite old and it cannot meet today's standards but the truth is that it is still good as an introduction to programming. I also learnt QBasic for two weeks before I moved to other languages like Java and C++.
I don't blame the people who are making jest of you and at the same time, i blame them because they were only making mouth and they didn't solve your problem. probably they do not no the solution to your problem. I have attached my own personal complete source code  and a QBasic interpreter to this post. The source code is CALCULAT.BAS and the QBasic program is QBASIC.EXE
You can also copy the source code from here. This code is one of the work i did in those days, but to keep up with today's standards, i now developed Calculator+.exe which I developed with Java.

REM CALCULATOR DEVELOPED BY OLADEJI OLUWASAYO
REM PRESS F5 ON YOUR KEYBOARD TO RUN THE PROGRAM
REM To operate the calculator input the first number, press enter, input the operation to perform(i.e + - * / sin because tan ^ &), press enter, then input the second number and press enter.
REM + means plus
REM - means minus
REM * means multiply
REM / means divide
REM ^ means raised to the power of(exponential)
REM & means root (e.g square root, cube root,  till any number root)

Most schools in Nigeria still do QBasic. The guy probably is still a student and QBasic happens to be the programming language they are starting with. Nobody is saying that QBasic is not old; but Nigerian schools still teach them. most universities in Nigeria still do QBASIC, FORTRAN, PASCAL and COBOL which people obviously will call obsolete languages. If you were to be in the guy's shoes would you tell your lecturer, HOD or VC that you will not offer those courses??

SayoMarvel  - Nice one for helping the guy out!

I doubt that most programmers end up working with their first (learned) programming language.  Many schools utilize simple or primitive programming languages to BRIEFLY introduce programming to students then they switch to other advanced languages. To determine which generation of programming language is the most suitable in learning programming is outside the scope of this thread. Criticizing the poor guy's choice of programming language doesn't help his situation either, If in the first place you do not know if it is a school requirement.

Please note that the "because" in that QBasic calculator source code is "COS".
Also note that all trigonometric functions are in capital letters i.e Sine is typed as SIN, Cosine is typed as COS and tangent is typed as TAN.
I also have a Calculator that I programmed in Java. Full GUI(Mouse Support), More Functionalities(Base Conversion), More User Friendly (atleast more than that of QBasic), and its layout is tailored to suit SUBSTANCE look and feel. So if you don't have it, the program may not look nice to you. I will attach that Calculator that I made with JAVA so that this our man that wants to learn QBasic will see why people said he should not waste his time on it. Just unzip It and execute "Calculator.class". I also found out that the QBasic.exe I posted earlier may not work, so I have attached another one that is working.
Good Luck Programmers,

Me, Myself & I.
