THREE TOP REASONS FOR LEARNING C

     <<<...THREE TOP REASONS FOR LEARNING C: ...>>>

*Good base for learning C++,C# or Java later

*Unix,Linux,Windows,Gaming frameworks are written in C

*Embedded systems programs are written in C

>>Constants = Literals->Cannot change

  Variable= Identifiers->May change

>>Types of variables and constants:1)Primary 2)Secondary

>>Three types in primary:

   integer

   real(float)

   Character

In a char constants,both quotes must slant to the left,like'A'

>>Variables has two meanings:

A.It is an entity whose values can change

B.It is a name given to a location in memory

>>variable names are case-sensitive and must begin with an alphabet'

>>Total keywords=32.Example char,int,float etc.

>>printf() is a function that can print multiple constants and variables

>>Format specifiers in print(),scanf():int-%i,float-%f,char-%c

>>main() is a function that must always return an integer values:

  o- if it meets success,I-if it encounters failure

>> Use /*... */ or // for a commnent in a program 

>>$is 'address' of operator and must be used before a variable in scanf()
