Suggestions for Essays and Speeches Writing

If getting started is the hardest part of the   writing process , close behind it (and closely related to it) may be the challenge of finding a ​ good topic   to write about. Of course, sometimes an instructor will solve that problem for you by   assigning   a topic. But other times you'll have the opportunity to choose a topic yourself, and you should really think of this as a great opportunity to write about something you care about and know well. So relax. Don't worry if a great topic doesn't immediately spring to mind. Be ready to play with a number of ideas until you settle on one that truly interests you.

Combinations : One of the things that computers are particularly good at is doing “the same thing over and over” in extremely tedious calculations. One of the applications for this is producing all the possible combinations of groups of things – for example, imagine you have 3 pennies in your pocket, and you flip them, one at a time, producing Heads(H), Tails(T), and Heads(H). Think of the sequence H,T,H as being one possible combination (outcome) of your coin flipping experiment. If we wanted to write a computer program to simulate ALL possible combinations of the flipping of your 3 pennies, the following algorithm would be just the ticket: int heads = 0; // let’s let the value 0 represent a heads coin toss int tails = 1; // let’s let the value 1 represent a tails coin toss for (int coin1 = heads; coin1 <= tails; coin1++) { for (int coin2 = heads; coin2 <= tails; coin2++) { for (int coin3 = heads; coin3 <= tails; coin3++) { String coin1str = ""; if (coin1 == 0) coin...
