I found this question in an old exam in computer science. I solved it in a good way, but I'm not convinced that my solution is the best solution, I believe that there's a better way to solve it.
Here's the question:
Given N Columns that are lined up, The horizontal distance between two adjacent...
I am complete beginner to cassandra, and here is my simple session on creating a table, it seems to be working, but am I doing something that is a bad practice in cassandra here?

I've been working on implementing Google Code Prettify and finally got it to work correctly. You can see my test file here to see what it looks like. I worked from a template and tried to improve it.

I'd just like to make a slight change to the code. When you are instantiating a StringBuilder, you have the opportunity to specify the capacity of it. Using this constructor, we can avoid having it resized more than necessary.
public String frontTimes(String str, int n) {

Resurrecting my C++ saga, I was given this project for my CS2 class:
This problem considers several ways to compute \$ x^n \$ for some \$ n
\ge 0 \$.
Write an iterative function power1 to compute \$ x^n \$.
Write a recursive function power2 to compute \$ x^n \$ using the following

A teacher gave my boyfriend the following question,
" Write a C++ program that allows the user to enter a time in seconds and then outputs how far an object would drop if it is in freefall for that length of time. Assume no friction or resistance from air and a constant acceleration of 32 feet pe...
Are there clear rules on when to use each of these when making classes and interfaces and dealing with inheritance?
I am working an a more meaningful way to print objects in VBA. The desired result should look something like this.
Console.PrintLine List.Create(1, 2, 3)
List(1, 2, 3)
The concept is that objects implementing an IPrintable interface are printed as their ToString property. Primitive data type...
I wrote this function for my next learning project (cfg parser). What do you think about it?
char readline(FILE *fp, char **line, size_t *size) {
*size = 0;
size_t cpos = ftell(fp);
int c;
while ((c = fgetc(fp)) != '\n' && c != EOF) (*size)++;
if (*size == 0 && c == EOF) {
