  In this program we have to find the number of vowels and consonant in a given string. This is a lex program so first we have to know how to run a lax program in ubuntu and what is the format of the program . The lex files are save in file_name.l and for running a lex file we use  some command which are given below:-


Code:-

%{
int ac=0;
int bc=0;
%}
%%
[aeiouAEIOU] {ac++;}
[a-zA-z] {bc++;}
%%
int yywrap() {}
int main()
{
printf("Enter the string \n");
yylex();
printf("THe number of vowel are %d\n",ac);
printf("The number of consonant is %d",bc);
return 0;
}

Output:-

 One more thing you have to know for terminate the program press Ctrl+d then it will print the output.

Enter the string

THe number of vowel are 8
The number of consonant is 12
