Will someone give some simple c++ tests?

[slashdot]

I'm not good with making programs up, though I should, I'll have to work on that later. But can someone make up a couple simple programs that I must figure out how to code? Don't write the code but let me figure out how to make it. Thanx .

Make me a simple bubblesort program. Then implement it in such a way so the client programmer can choose whether he wants to sort by ascending order or sort by descending order.

- Forward the results to standard iostream.
- Initialize a std::string array.
- Let the sorter sort arrays.
- Don't implement anything that has nothing to do with this assignment. No menu's etc.
- Use descriptive names.
- Implement app in your namespace, e.g.

namespace slashdot
{
}

Reverse Polish Notation is a way of writing mathematical notation in which the operators go after the arguments, which does not require parentheses. For example, 3 5 + simplifies to 8, and 4 7 * simplifies to 28. If you write 1 2 3 + +, first the 2 3 + simplifies to 5, then 1 5 + simplifies to 6. The quadratic formula, normally written (-b + sqrt(b*b - 4*a*c)) / (2 * a), would be written as

b b * a c * 4 * - sqrt b - 2 a * /

RPN calculators use a stack to evaluate their expressions, and a basic four-function RPN calculator can be written in one line of Perl. Write one in C++. Search on the Web for more information.

I first read this recommendation in a response to an Ask Slashdot question, by the way :-)

No, I gave slashdot this task for a good reason. It is *exactly* the same task I give profesional junior coders. From there we'll build up something. The whole purpose is to see what design is all about. My assignment is the first step out of a few.

[slashdot]

thats too advance for me. Maybe a simple game or something would do better. But if you give me a good reason why I should go ahead and try to make your program tell me, and I'll be on my way.

[Valmont]

Do you know how to make basic classes?

[slashdot]

Actual Val (is Val alright?) I don't think I know how to make classes. I have only been read somewhere around 120 pages in C++ for dummies and a couple sources online. So ya, I'm not pro C++ haxer yet. Maybe a simpler test. I'm not sure what to tell you other then I've only goten up to pointer variables.

[Valmont]

Make code that removes the first encountered substring from a C-style string.
I want you to explain every line of code. You need to prove you'understand char* handling.

Like this:
char* theString = "Life is hard, then you die.";
remove_substring(theString, "hard");
//theString = "Life is, then you die."

[slashdot]

Ok sry if I am complaining to much, but those seem to hard for me. Heres what I have read so far...

Initializing variables, boolean statements, functions, loops, pointers, pointer variables (I think), and now I'm am reading on classes. There may be a couple more I am missing, but I am sure it can be filled in easily.

[Belisarius]

That second example is really pretty simple - you should be able to do it with only the programing elements you said you've covered.

Learn the ways of:
strcat, strcpy, strncpy, strncat
I do this for a purpose you know. If you don't know about functions then no problem whatsoever. Just make everything work in main().

Hey you know what I just got past those in my book the other day. I'll take a crack at your quiz alright? I'll be back with it in a day or a day and half.. thanx for taking some time to make a quiz for me!

If you want the answer just open chapter 4 of "The C Programming Language"

Also if he's new to programming thats probably way over his head.
