Create a subfolder called bin and place it in your path. Put command (.bat) files and other frequently-used executables in that directory. See system configuration for details.
You must make the appropriate changes to your path. For Microsoft Visual C, use the command file vcvars32.bat from the command window. For Java, insert the SDK bin folder into your path. To run Python directly from the console you need to have the Python installation directory in your path.
I copied the vsvars32.bat into my bin directory and renamed the file vc.bat. Then I just type the command vc to define the Visual C environment.
You could also create a command file to add the Java bin directory to your path, for example:
set PATH=%PATH%;C:\Program Files\Java\jdk1.6.0\bin
To compile a C program:
cl /W4 AddArray1.c
To compile a C++ program:
cl /EHsc /W4 AddArray.cpp
C:\prog\intro>cl /EHsc AddArray.cpp /FemyArray.exe Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 14.00.50727.42 for 80x86 Copyright (C) Microsoft Corporation. All rights reserved. AddArray.cpp Microsoft (R) Incremental Linker Version 8.00.50727.42 Copyright (C) Microsoft Corporation. All rights reserved. /out:myArray.exe AddArray.obj C:\prog\intro>myArray C++ version: sum is 45
Compiling a C/C++ program produces an object module
Example: AddArray.obj
Object modules are linked to produce the executable file
Example: AddArray.exe
You run the executable file (console programs) by typing its name in the command window
Example: AddArray.
To compile a Java program:
javac AddArray.java
To run a Java program:
java AddArray
The filename must match the public class name used for the Java program. Java program names are case sensitive!
If you have a filename AddArray.java, you must declare a class called AddArray.
When you compile, you must use the java extension:
javac AddArray.java
When you run a java application, you do not use the class extension:
java AddArray
To compile: javac AddArray.java
To run: java AddArray
The java compiler (javac) takes java source files (.java) and generates java class files (.class). A class file is a stream of Java tokens (bytecode) that is interpreted by the Java virtual machine.
Java is executed by the java program (java) using a java class file containing a static main method.
To run Python from the command window, you must add the Python installation directory to your path, then you can run Python scripts as shown:
C:\work\python>set PATH=%PATH%;C:\python25 C:\work\python>python addarray.py The sum is 45
You can also run Python interactively:
C:work\python>python Python 2.5.1 (r251:54863, Apr 18 2007, 08:51:08) [MSC v.1310 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> print "Hello World!" Hello World! >>> quit()
