C++ code

please use cout and cin

a. Write a CH program that asks the user to enter N, the program should then output the Fibonacci series. Use do-while loop to ask user to re-enter N if the user entered a number below 2. Hint: The first two numbers in the Fibonacci series are 0 and 1. [5 marks] F, = 0 F = 1 Any Fibonacci number is equal to the summation of the two previous numbers Fn = Fn-1 + Fn-2 Therefore, F = F. + Fo = 1 + 0 = 1 F3 = F2 + F = 1 + 1 = 2 F = F3 + F2 = 2+1=3 Fn = FN-1 + FN-2 Enter N: 20 011 2 3 5 8 13 21 34 55 89 144 233 377 610 987 1597 2584 4181 6765 b. Write a program that use loops to print the following patterns separately, one below the other. In your code use for, while and do-while loops to generate the patterns, use one loop for each question. 15 marks] AAAAA BBBB CCC DD E
