- C is a programming language developed at AT and t`s bell laboratory. It was written and invented by a man named "Dennis Ritchie" Ritchie seems to have been rather surprised that so many programs preferred C to older language like "FORTRAN OR PPL/I."C seems so population because it is reliable, simple and easy to user for their work.
- in these is the language of choice while building such operating systems programs.
- C++,C# and JAVA make use of a principle called OOP(Object Oriented Programming) to organize the program. this organizing principle has lots of advantages and to offer but even while using the organizing elements of C and the base programming skills.
- Major parts of popular operating systems like WINDOWS, UNIX, LINUX excetra language are still written in C language. many popular gaming frameworks have been built using C language.
- instead of starting how to begin programs, we must know the alphabets, numbered and special symbols are used in C than how constant, variable and keywords are constructed and finally how are this combine to form and group of instructions would be combined to form a program.
- .. Step 1 : Alphabets, Digits and Special symbols.
- Step 2 : Constants, Variables and Keywords.
- Step 3 : Instructions.
- Step 4 : Programming .
STEP 1: alphabets, digits and special symbols.
A C character C denotes any alphabet digit and special symbol used to represent the information.
Include : A TO Z and a to z (capital and small both are valid).
Digit : 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Special Symbols : ~ ! @ # $ % ^ * ( ) " . / + , - { } ; ' > ?
Step 2 : constants, variable, keywords.
Step 1 is combined with step 2 that means the alphabet, digit and special symbol when properly combined with constant, variable and keywords now we understand the meaning of each of them.the constant is an entity that doesn't change. variable is entity it may change .
STEP 3 : INSTRUCTION
A programs is nothing but a set of instruction. the program behaves as per the instruction that we give in it. Different instruction make different tasks in a program.
there are three types of instruction.
1) variable type instruction.
2) arithmetic instruction.
3) control instruction.
STEP 4 : PROGRAMMING
FIRST THREE STEP COMBINED AND MAKE A STEP 4.
