just started c++ class.... we use the absolute c++ book

after starting to read this book i decided to buy c++ for dummies and borrowed a book titled object oriented programming with c++ (book is from india written in english)

i still have no idea where to start on these two problems...
can someone dummy them down to basics and concepts... i dont want the code as i would like to learn this instead of just get the coding.

2. A government research lab has concluded that an artificial sweetener commonly used in
diet soda will cause death in laboratory mice. A friend of yours is desperate to lose
weight but cannot give up soda. Your friend wants to know how much diet soda it is
possible to drink without dying as a result. Write a program to supply the answer. The
input to the program is the amount of artificial sweetener needed to kill a mouse, the
weight of the mouse, and the weight of the dieter. To ensure the safety of your friend,
be sure the program requests the weight at which the dieter will stop dieting, rather
than the dieterâ€™s current weight. Assume that diet soda contains one-tenth of 1% artificial
sweetener. Use a variable declaration with the modifier const to give a name to this
fraction. You may want to express the percentage as the double value 0.001.

8. The Babylonian algorithm to compute the square root of a number n is as follows:
1. Make a guess at the answer (you can pick n/2 as your initial guess).
2. Compute r = n / guess.
3. Set guess = (guess + r) / 2.
4. Go back to step 2 for as many iterations as necessary. The more steps 2 and 3 are
repeated, the closer guess will become to the square root of n.
Write a program that inputs an integer for n, iterates through the Babylonian algorithm
be most accurate for small values of n.

Basically, you have to turn the description into a set of quations. This has nothing to do with C++, yet.

A friend of yours is desperate to lose weight but cannot give up soda. Your friend wants to know how much diet soda it is possible to drink without dying as a result.

Assume that diet soda contains one-tenth of 1% artificial sweetener. Use a variable declaration with the modifier const to give a name to this fraction. You may want to express the percentage as the double value 0.001.

Given the inputs described above, these ratios are useful and equivalent: SweetenerFriend / WeightFriend = SweetenerMouse / WeightMouse We know 3 of the 4 items, so rewrite as: SweetenerFriend = (SweetenerMouse / WeightMouse) * WeightFriend This gives you the amount of sweetener that will kill your friend.

Last thing to calculate is amount of soda. Since sweetener is 0.1% of the soda (or 0.001), you need to figure out how much soda is needed to get SweetenerFriend amount of the deadly chemical... This I leave to you...

Once you have the equations, it should be a simple matter to plug them into a program -- that is if you know programming ;) Do what you can and post your attempt and we'll help you clean it up.

I find it humorous that there was a google ad for aspartame resources just under tatumkay's post when I first read it. :lol:
