Program Listing

program CountVowelsAndConsonants;


var

   inputStr: string;

   numVowels, numConsonants: integer;

   i: integer;

   currentChar: char;


begin

   numVowels := 0;

   numConsonants := 0;

   writeln;

   write('Vowels and Consonants in Pascal');

   writeln;

   writeln;

   write('Enter a string: ');

   readln(inputStr);

   

   for i := 1 to length(inputStr) do begin

      currentChar := upcase(inputStr[i]);

      if (currentChar >= 'A') and (currentChar <= 'Z') then begin

         if (currentChar = 'A') or (currentChar = 'E') or (currentChar = 'I') or (currentChar = 'O') or (currentChar = 'U') then begin

            numVowels := numVowels + 1;

         end

         else begin

            numConsonants := numConsonants + 1;

         end;

      end;

   end;

   

   writeln;

   writeln('The number of vowels in the string is: ', numVowels);

   writeln('The number of consonants in the string is: ', numConsonants);

    writeln;

   write('End of Program');

   writeln;

   readln;

end.
