Algorithm:-
begin
if a,e,I,o,u or A,E,I,O,U
then
printf It is a vowel
else
printf It is a consonant
end

1. LEX program to count number of vowels and consonants in a given input string

%%
{printf( it is vowel );}
{printf( it is consonant );}
%%
main()
{
yylex();
}
int yywrap()
{
return 1;
}

Output:

$./a.out
a
it is a vowel
g
it is a consonant ....etc

Prime number program in c: c program for prime number, this code prints prime numbers using c programming language. To check whether a number is prime or not see another code below. Prime number logic: a number is prime if it is divisible only by one and itself. Remember two is the only even and also the smallest prime number. First few prime numbers are 2, 3, 5, 7, 11, 13, 17..etc. Prime numbers have many applications in computer science and mathematics. A number greater than one can be factorized into prime numbers, For example 540 = 22*33*51 ....etc

lex code for prime number

Lex is a computer program that generates lexical analyzers (scanners or lexers).Lex is commonly used with the yacc parser generator. Lex, originally written by Mike Lesk and Eric Schmidt and described in 1975,is the standard lexical analyzer generator on many Unix systems, and an equivalent tool is specified as part of the POSIX standard.Lex reads an input stream specifying the lexical analyzer and outputs source code implementing the lexer in the C programming language. ....etc
