Borland Turbo Pascal v1.5 for Windows

NOTES  |  To Make It Work  |  Example Program  |  Judges Information

• NOTES:

  • You must not try to use the debugger!!! It does not work and will crash the system (Turbo Pascal at least)!
  • You must have the uses WinCRT; at the top of your program to get output (if you are planning to do I/O with the keyboard and the screen).
  • You should only use READ, READLN, WRITE, and WRITELN (if you are plannig on doing keyboard/screen I/O).
  
  

• To Make It Work:

  You can trick standard I/O to reading from a file and writing to a file by doing the following:
  • At the top of the program, after the program declaration and before the var declaration, make sure there is

    	uses WinCRT;
    		

  • In the body of the program, after the main begin declaration, make sure there is

    	Assign(Input,'input.txt'); Reset(Input);
    	Assign(Output,'output.txt'); Rewrite(Output);
    		

  • At the end of the main program, before the end. declaration, make sure there is

    	Close(Output);
    		

  
  

• Example Program:

  	program Welcome;
  
  	uses WinCRT;
  
  	var
  	  name: string;
  
  	begin
  	  Assign(Input,'input.txt'); Reset(Input);
  	  Assign(Output,'output.txt'); Rewrite(Output);
  
  	  Readln(name);
  	  Writeln('Welcome to Turbo Pascal for Windows, ',name);
  
  	  Close(Output);
  	end.
  	

  Items in red are the needed additions for file I/O using standard I/O commands.
  
  

• Judges Information:

  • Look at the source for:
    • Make sure there is a uses WinCRT; section
    • Make sure the following two lines just after the begin of the main program (if they aren't already there):
      Assign(Input,'C:\TEMP\test.in'); Reset(Input);
      Assign(Output,'C:\TEMP\test.out'); Rewrite(Output);
    • Make sure the following line just before the end. of the main program:
      Close(Output);
    If any of these sections aren't there, return IS - Improper Submission

Microsoft QBasic

NOTES  |  To Make It Work  |  Example Program  |  Judges Information

• NOTES:

  • Write your code to do keyboard input(INPUT) and ouput (PRINT).
  • Make sure you use the TEST button from PC²
  
  

• To Make It Work:

  Refer to the other sections of QBasic.
  
  

• Example Program:

  DIM cows AS INTEGER
  DIM total AS INTEGER
  
  total = 0
  INPUT cows
  WHILE (cows > -10)
  	total = total + cows
  	INPUT cows
  WEND
  PRINT "A herd of ",total," cows."
  END
  

  
  

• Judges Information:

  • You will need to exit the QBasic window (Under File, select Exit)

Microsoft Visual Basic v5.0

NOTES  |  Example Program  |  Judges Information

• NOTES:

  • When you create your project, just select the standard.exe, not a GUI. Use only one form for your application. Submit only your form file (we just need the form source-- not the whole project).
  
  

• Example Program:

  	Private Sub Form_Load()
  	Close #1
  	Open "c:\temp\input.txt" For Input As #1
  	Dim b As Integer, c As Integer, d, e, f As Integer
  	Dim aa As Integer, bb   As Integer, cc As Integer
  	b = 1
  	While b <> 0
  	Input #1, b
  	Input #1, c
  	f = b * c
  	Open "c:\temp\output.txt" For Append As #2
  	Print #2, f
  	Close #2
  	Wend
  	Close #1
  	Unload Me
  	End Sub

Microsoft Visual C/C++ v5.0

NOTES  |  To Make It Work  |  Example Program

• NOTES:

  • When creating a new project, make sure you select Win32 Console Application for the project type!
  • When creating a new source file, choose C++ Source File and let it append a .cpp to your filename (this works even if you only code in C).
  • Your project should have only one .c or .cpp file only.
  
  

• To Make It Work:

  • Under the Build menu, select Rebuild All to compile.
  • Under the Build menu, select Execute <filename> to run.
  
  

• Example Program:

  	#include <stdio.h>
  
  	void main()
  	{
  	 char name[80];
  
  		printf("What's your name? ");
  		scanf("%s",name);
  		printf("\nHello World!, %s\n",name);
  	}
