Program 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.
