Homework #1: C++ Basics, Flow of Control, and Function Basics By J. H. Wang Mar. 13, 2015

Programming Exercises Write a C++ program that allows the user to repeatedly enter integers until she inputs a 0 (zero). Then, your program should do the following: (a) count the number of positive values and the number of negative values in user input; (b) calculate the sum and average of the numbers; [Note: Do not count the ending input 0 in the result.] [Note: Please do not use arrays because you don’t need them in this exercise.]

Programming Exercises A formula for calculating annual compound interest is: F=P(1+r)n where P is the present value, r is the interest rate per year, n is the number of years. Write a C++ program that asks the user to input integers n and P, a double r between 0 and 1, and computes the future value of F. [Note: Please do not use the predefined math functions such as pow().]

One way to estimate the height of a child is to use the following formula, which uses the height of the parents: Hmale_child=((Hmother13/12)+Hfather)/2 Hfemale_child=((Hfather12/13)+Hmother)/2 All heights are in inches. Write a function that takes as input parameters the gender of the child, height of the mother in inches, and height of the father in inches, and outputs the estimated height of the child in inches. Embed your function in a C++ program that allows you to test the function over and over again until telling the program to exit. The user should be able to input the heights in feet and inches, and the program should output the estimated height of the child in feet and inches. Use the integer data type to store the heights.
