Overview of C

History of C :-

• Developed at Bell Laboratories in the early seventies by Dennis Ritchie.
• C introduced such things as character types, floating point arithmetic, structures, unions and the preprocessor.
• The principal objective was to devise a language that was easy enough to understand to be "high-level" – i.e. understood by general programmers, but low-level enough to be applicable to the writing of systems-level software.
• In 1978, Brian Kernighan and Dennis M. Ritchie wrote the seminal work The C Programming Language, which is now the standard reference book for C.
• A formal ANSI standard for C was produced in 1989.

The Compile Process :-

_____________________________________

Flowchart is a diagrammatic representation of sequence of logical steps of a program. Flowcharts use simple geometric shapes to depict processes and arrows to show relationships and process/data flow.

Symbol	Symbol Name	Purpose
	Start/Stop	Used at the beginning and end of the algorithm to show start and end of the program.
	Process	Indicates processes like mathematical operations.
	Input/ Output	Used for denoting program inputs and outputs.
	Decision	Stands for decision statements in a program, where answer is usually Yes or No.
	Arrow	Shows relationships between different shapes.
	On-page Connector	Connects two or more parts of a flowchart, which are on the same page.
	Off-page Connector	Connects two parts of a flowchart which are spread over different pages.

Guidelines for Developing Flowcharts :-

These are some points to keep in mind while developing a flowchart −

• Flowchart can have only one start and one stop symbol
• On-page connectors are referenced using numbers
• Off-page connectors are referenced using alphabets
• General flow of processes is top to bottom or left to right
• Arrows should not cross each other.

First Program :-

                    HELLO WORLD

Flowchart :-

 

PROGRAM

#include<stdio.h> int main() {             printf("HELLO,WORLD!"); }

OUTPUT:- HELLO,WORLD!
