Python Programming Language
Python is commonly used for developing websites and software, task automation, data analysis, and data visualization. Since it’s relatively easy to learn, Python has been adopted by many non-programmers such as accountants and scientists, for a variety of everyday tasks, like organizing finances.
History of Python
Who invented Python? Guido van Rossum. When he began implementing Python, Guido van Rossum was also reading the published scripts from “Monty Python’s Flying Circus”, a BBC comedy series from the 1970s.
Meaning of C Programming Language
The language has been given the name C because it succeeds another language called B. C is one of the most popular computer programming languages which has existed since the last 44 years. It was created by the famous American programmer Dennis Ritchie – with the help of Ken Thompson – while working at Bell Labs.
System Calls in C

What is system cls in C? Using system("cls") – For TurboC Compiler system() is a library function of stdlib.h header file. This function is used to run system/command prompt commands and here cls is a command to clear the output screen.
Need for Calling fflush
For disk file streams call fflush() after all writing has been done. Its not necessary to call fflush() before the file is closed because fclose() will do that anyway. There are two implicit flushing "routines": When a newline character is sent to the output stream in question.
Relationship Between fflush and fsync
Does Fflush call fsync? But is that the case: is there a call to fsync from fflush? No, calling fflush on a POSIX system does not imply that fsync will be called.
