Identifiers

The identifiers are user defined names used in programs for providing names to variables, arrays and functions. The identifiers are made up of letters(uppercase and lowercase), digits and underscore(_). For Example, int max ; //max is an identifier which have datatype integer int max2; //this is second identifier of same datatype string max_3; //you can also use identifier like this with different datatype and underscore float 4max ; //you can not declare identifier like this this will generate an error The C is case sensitive and hence the uppercase and lowercase letters are not treated as same. For Example, int max=20 ;// this is a different variable which assigns a value 20 to max int Max=10 ; //this is different variable which assigns a value 10 to Max Identifiers also used to identify functions. For Example, int Add() ; //this is a Function which is created for addition of two integer; Program Aim : - This Program will help you ...
