1. 1. Write a program to delete all vowels from a sentence. Assume that the sentence is not more than 80 characters long.
   2. Write a program to calculate the factorial of a number using recursion.
2. 1. Write a program to print out all Armstrong numbers between 1 and 500. (If sum of cubes of each digit of the number is equal to the number itself, then the number is called an Armstrong number).
      e.g. 153 = (1 * 1 * 1) + (5 * 5 * 5) + (3 * 3 * 3)
   2. Write a program to subtract two matrices.
3. 1. Write a program to calculate the sum of the first and last digits of any given numbers.
   2. Write a program to plot a given function y = x²
4. 1. Write a program to calculate the G. C. D. of two positive integers recursively
   2. Write a program to print any give line of text backwards.
5. 1. Write a program to add and subtract 2 complex numbers.
   2. Write a program to analyze a line of text to count vowels, consonants and digits using pointers.
6. 1. Write a program to find the binary equivalent of a given decimal number.
   2. Write a program to sort a list of given names in ascending order.
7. 1. Given 50 pairs of length and breadth of rectangles, write a program to find all rectangels whose areas are greater than their perimeters.
   2. Write a menu driven program to find:
      1. Factorial of a given number.
      2. Whether a number is even or odd.
      3. Whether a number is prime of not.
8. 1. Write a program that will print out all rotations of a string typed into it.
      e.g. Rotations of the word 'BOY' are 'OYB', and 'YBO'.
   2. Write a program that implements a calculator.
9. 1. Write a program that uses a function power(a, b) to calculate the value of a raised to b.
   2. Write a program to analyze a line ot text to count vowels, consonants and digits using pointers.
10. 1. Write a program that will produce the following output:
       
       

       *	*	*	*
       *	*	*
       *	*
       *

    2. Write a program to calculate the value of the n^th Fibonacci number using recursion.
11. 1. Write a program to concatenate a string to the left of of a given string.
    2. Write a program to calculate the average of a list of positive data using data validation.
12. 1. Write a program to delete all occurrences of the word 'the' from a given line of text.
    2. Write a program to calculate roots of a given quadratic equation.
13. 1. Given 3 variables x, y, z; write a program that uses a function to circularly shift their values to right. (If x = 5, y = 8, z = 10, after a circular shift, the output shall be y = 5, z = 8, and x = 10).
    2. Write a menu driven program to find:
       1. Factorial of a given number.
       2. Whether a number is even or odd.
       3. Whether a number is prime or not.
