If character in ch is not a vowel, return -1.
16. Write a main function to input a string and a character. Print the occurance of ch in str by invoking the function countvowels().
17. Specify the class finder with the following overloaded functions :
i. int findmax(int n1, int n2) to decide and return largest from ni and n2. If both the numbers are same then return 0.
ii. int findmax(int n1,int n2,int n3) to decide and return largest from n1,n2 and n3. If all the numbers are same then return 0.
