Thread: Quick question arrays/pointers

First off: I'm not asking anyone to do any programming for me

Just as simple an answer as you can give that answers the question as I'd like to do the work/figure most of it out on my own.

Quick prompt:

Write a program which generates interactive stories. You
program should begin by asking the user a number of questions such as: what is your name? How old are you? What is your favorite color? Etc. After obtaining a sufficient amount of personal information your program should output a short story which incorporates user’s personal information you have obtained via questioning. The generated story should be somewhat different if the program is run a few times (randomly generate alternative endings, randomly select different descriptions of objects (blue car, green car, red car), etc. Your program should make use of pointers and arrays to deal with strings.

Sample Output:
What is your name? Roman
How old are you? 29
What is your favorite color? black
Roman is a 29 year old who likes his black laptop…

Sample Output (second run of the same program):
What is your name? Roman
How old are you? 29
What is your favorite color? black
Roman is a 29 year old who likes his black Toyota Corolla...

The one thing I'm a bit held up on is how to make the paragraph generate random events/descriptions/etc. Obviously I need to use arrays/pointers, but I'm not exactly sure what to use and the logic behind it.

Any bit of help or minor pointing in the right direction would be great. Give me some direction and I'll hunt it down/work it out myself. I know it's relatively easy, I'm just not grasping it so...

Have you looked at rand()?

Create an array that holds the "alternate endings." Look at rand(), as previously stated by tabstop, and use the returned number to choose the array index.

I lied

Read through my C book on arrays and couldn't quite find a way to store multiple values in a single array.

Would it just be something like

Code:

cRandomColor[4] = {blue, red, green};

Arrays are simply collections of values which are accessible via a numeric index. Sure arrays hold multiple values... that's what they do best.

Maybe something like the following:

Code:

char *cRandomColor[4] = {"blue" , "red" , "green", "yellow" };

I also lied, liljp617. I don't really know how to program... I just copied off of my neighbor in programming class
