maintsv (sys.argv[1]) Accepts the program file (Python program) and the input file (C++file) as a list(array). argv[0] contains the Python program which is need not to be passed because by default _main_ contains source code reference and argv (1) contains the name of the C++ file which is to be processed.

The "cd"command refers to changes directory and absolute path refers to the complete path where Python is installed.

Executing C++Program through Python
(i) Double click the run terminal of MinGW
(ii) Go to the folder where the Python software is located (Python.exe) is located.
For example here "Python" is located in

g++ is a program that calls GCC (GNU C Compiler) and automatically links the required C++library files to the object code

(i) Python deletes unwanted objects (built-in types or class instances) automatically to free the memory space.
(ii) The process by which Python periodically frees and reclaims blocks of memory that no longer are in use is called Garbage Collection.

'cd' command refers to change directory and absolute path refers to the couple path.
(Eg) "cd c:\program files\open office 4\program"

Modular programming is a software design technique to split our code into separate parts. These parts are called modules. The focus for this separation should have modules with no or just few dependencies upon other modules.

(i) SWIG - Simplified Wrapper Interface Generator
(ii) MinGW - Minimalist GNU for Windows

S.No	Compiler	Interpreter
(i)	It takes an entire Program at a time.	It takes a single line of code or instruction at a time.
(ii)	Display all errors after compilation, all at the	Displays error of each line one by one.

(i) The theoretical difference between the two is that scripting languages do not require the compilation step and are rather interpreted.
(ii) For example, normally, a C++ program needs to be compiled before running whereas, a scripting language like JavaScript or Python need not be compiled.
(iii) A scripting language requires an interpreter while a programming language requires a compiler.
