//semicolon is used to terminate a particular statement.

//every single object of a c program is called a token.

//basic tokens are keywords, identities, string literals

& symbols.

// keywords are some reserved words in c programming like int

return etc

// identifier is just a name given a variable or constant.{a-z}

// all the panctuation marks just @#%^& are not  marked as

identifiers.

// c is a case-sensitive programming in which h & H is different.

//In the following program 0 is a constant. any number is

a constant cause it has a specific value.

//Here the main statement is hello world which is a string

literal.

// &a, &b is basic symbols of c programing.

// blank or white spaces dosen't metters.

//importent there must be an space between each and

every single token.
