EXAMPLE 1 The QBASIC program will, automatically, *capitalize* any reserved 'keyword' which it finds once you've already gone and typed in a line of code; and, then, at the end of that code line, do finally press the [RETURN/ENTER] key...to confirm what you've just gone and typed in. A keyword might be say the PRINT command statement...so, if I were to type inside of the QBASIC editor the following line of code... print 1+1 ...then, the moment I press the [RETURN/ENTER] key when I get to the end of that line...the QBASIC interpreter program will, automatically, change the 'lower case' word: print...to become all UPPERCASE, instead; QBASIC Editor will display the previous line of code I typed in as being... PRINT 1+1 ...thus, I am able to tell immediately that PRINT is a special reserved 'keyword'/or, command statement which the QBASIC program, quite clearly, recognizes and understands. This also helps me the programmer to know if I actually typed in that 'keyword' either correctly/or, incorrectly; if wrong...and, the program did NOT automatically capitalize it...; then, I know I must have either accidentally 'misspelled' the keyword/or, must otherwise have done something to go get it wrong...?! EXAMPLE 2 If I were to type in to the QBASIC Editor program the following line of code using all 'lower case' letters... x=10: if x=10 then print "ten" else print "NOT ten" ...and, then, when I've reached the end of that line of code, press [RETURN/ENTER] key to confirm my code entry; the QBASIC interpreter program will, automatically, respond by capitalizing any reseved 'keywords' that it finds; then, QBASIC Editor displays the line of code I typed in as being... x=10 : IF x=10 THEN PRINT "ten" ELSE PRINT "NOT ten" Looking at this newly capitalized line...it tells me that... IF/THEN/ELSE/PRINT...are all QBASIC reserved 'keywords'. NOTE: Whatever is a string a text that is written in between double quote marks: ("") will be totally unaffected by such capitalizing; instead, text strings will be printed out, quite literally, 'as is'. FINAL NOTE There are far too many QBASIC 'keywords' for me to go and list here; possibly, a couple hundred...! QBASIC has many 'keywords' that it uses; if you wish to see what ALL of these keywords are; then, from inside of the QBASIC Editor program itself...do a combination key press of: [SHIFT] + [F1]...and, there you will see the Help file...that shows each 'keyword' you can use to write QBASIC programs with; as well as, offering a clear explanation/it shows 'example codes' demonstrating exactly how each of these 'keywords' should be used; just do 'copy & paste'/then, RUN the program to follow these examples along.
Try the triangle program on a search engine. Replace numbers with stars and that should do the trick

The flowchart in deriving the sum of two numbers, you may follow the steps provided below:Draw the start symbol then a flow line connecting to item #2Draw the init box for the syntax: set variable_Sum=0, Variable_A=0, Variable_B=0 then a flow line connecting to item #3Draw the first input box and write variable_A then a flow line connecting to item #4Draw the decision box for 'Is variable_A not numeric?'. if yes, draw a flow line connecting to item#3 else draw a flow line connecting to item #5Draw the second input box and write variable_B then a flow line connecting to item #6Draw the decision box for 'Is variable_B not numeric?'. if yes, draw a flow line connecting to item#5 else draw a flow line connecting to item #7Draw the process box for the syntax: compute variable_Sum=variable_A + variable_B then a flow line connecting to item #8Draw the output box and write variable_Sum then a flow line connecting to item #9Draw the end symbol.
first draw a small line and write 70 on the top and 100 at the bottom.you read it like this 70 out of 100.
A C++ program can be used to write C programs that will display 10 lines of biodata. Many types of C programming can be written with a C++ program.
the command "display" brings up the ImageMagick program.

IF THE QBASIC IDE/INTEGRATED DEVELOPEMENT ENVIRONMENT *IS* ALREADY OPEN Inside of QBASIC IDE/Integrated Development Environment...; you load in QBASIC programs as follows... 1. Use your mouse to click the QBASIC Menu option being seen top right... File > Open ...then, browse through the file list box to load your chosen program file. 2. Alternatively, you can also use keyboard short cut... [ALT]+[F], this opens up the file menu...then, press [O] ...does exactly the same as above IF THE QBASIC IDE/INTEGRATED DEVELOPMENT ENVIRONMENT IS *NOT* ALREADY OPEN 3. Another way is to open up a command line window prompt: (>)... Click [Start] button ...then, type: Command .../or, type: Cmd ...at least, one of the above should work... ...and, run the QBASIC program from there... by typing in after the command line prompt: (>)... c:\> cd, means, change directory folder... cd C:\pathToQbasic For example the file path name to where my version of QBASIC is stored here... c:\basic\qb64 So, I would first change to this folder directory by typing in after the prompt: (>)... c:\>cd c:\basic\qb64 ...this changes my command line prompt: (>) to say... c:\basic\qb64> Inside of the [qb64] folder directory, I wrote a very simple program called: hw.bas ...which contains the following single line of code... PRINT "Hello, world!" I can launch both the QBASIC program: [qb64.exe]/and, at the same time load in my chosen program file: [hw.bas], by typing after the command line prompt: (>)... C:\Basic\qb64>qb64 hw.bas ...the QBASIC program instantly loads: [qb64.exe]/with the program file [hw.bas] already being displayed inside of the Editor Screen. Next, I only need to press function key [F5] to RUN/make that program file execute... QBASIC Output Screen... Hello, world! Press any key to continue...

The QBASIC program actually comes in 2 different flavors... A> QBASIC interpreter program: QBASIC Version 1.1 B> QBASIC compiler program: QBASIC 4.5/or, QB64/or, -etc. ...so, the answer is that this programming language comes in both forms: 'interpreter/compiler' versions; and, you have to select which of these you would prefer to download and use. *NOTE*: The compiler version of the language tends to be much larger; whereas, the interpreter version of the language tends to be small/very compact, indeed; thus, the interpreter tends to take up far less disk space. Many people start off their programming career by using QBASIC version 1.1 'interpreter' program; in order to learn 'how to' program. The interpreter version of the program can only create plain text (.bas) files; the which code CANNOT be shared with others; (not unless the persons who you are sharing this type of code with do already have a copy of the QBASIC interpreter program installed on their own computer). Then, later on, down the line...when they have become fully capable programmers themselves; they go and download a QBASIC 'compiler' program version, instead; which will allow them to go and create stand alone (.exe) program files that they can share with anybody. This is because (.exe) program files can RUN/execute entirely independently of the QBASIC program itself.
QBASIC GRAPHICS There any many different things you can draw in QBASIC; ranging from... -dots -lines -rectangles -circles -shapes empty/or, filled in(painted) -you can even do LOGO style programming to draw graphics with; by joining up connected lines -animations are possible, too ==== QBASIC BUILT-IN HELP FILE + CODE EXAMPLES In order to view the QBASIC built-in Help file...; first, load the QBASIC program itself...; and, then, do a combination key press of: [SHIFT] + [F1] Use the built-in QBASIC Help file to learn more about how to use these 'graphic related' commands, and, more...! The QBASIC Help file also contains plenty of 'example codes'; which you can just use 'copy & paste'; then, RUN...to see what the output effect will be...???

Before QBASIC there was... BASIC BASICA The QBASIC programming language is a modern form of old BASIC programming languages which came before it; these older BASIC's used such things as, line numbers. 10 PRINT "Hello, world!" : REM *** Old BASIC line statement QBASIC code, however, doesn't need to use line numbers, anymore; and, this creates much simpler/clearer/cleaner code/which is also quicker to write/debug. PRINT "Hello, world" '*** QBASIC line statement However, now-a-days, QBASIC is a rather outdated programming language which has been superceded by... VB/Visual BASIC VBA/Visual BASIC for Applications VBScript/Visual BASIC Script VB.NET/Visual BASIC.NET VB.NET, is the latest BASIC programming language version offering from the software company, Microsoft. The Visual BASIC family of programming languages uses OOP/Object Oriented Programming techniques; where you can use a library of pre-built software objects; this makes coding much faster...leading to RAD/Rapid Application Development...because it means that by making full use of these re-usable software objects; then, programmers can write much less code; which in some cases can cut software development time down by half/or, more...!
