Explanation

Get a String using fgets() function. 
Str -> reads the string and stores it in str.
50 -> reads maximum of 50 characters
stdin-> reads character from keyboard

store vowels in array s.

for loop iterates and check each character whether it is  in array s using inner for loop. if it is in s, then increment count.

Finally prints count.
