Q. 2. DAC to accept a sentence. Print all the words that start with a vowel and end with a consonant. For example :

  1. to find and print the largest out of the two integers
  2. to find and print the largest out of the three integers
  3. to find and print the largest out of the three real numbers

Q. 4. DAC amicable(int,int) with a default constructor, a parameterized constructor and the following two functions :

  1. checkAmicable(int,int) – this function returns true if the two arguments are amicable otherwise it returns false.

Hint : a pair of numbers are amicable if the sum of the factors of one number (excluding itself) is equal to the second number and vice-versa.

Q. 5. Design a class to enter a sentence in lower case. Encrypt the string and print. For example :
