Separate “for” loop iterations
How would I go about making each iteration of my four loop be random. The outcome as of now makes all 20 sentences put the same output, although it is choosing random words each time from the four arrays created in static class OuterWord.

I need to write a simple Java program so as to step through a given string (given from args[]), and receive a println once a certain character (e.g. ‘^’) is encountered. However, I cannot find why I …
How much to grow buffer in a StringBuilder-like C module?
In C, I’m working on a “class” that manages a byte buffer, allowing arbitrary data to be appended to the end. I’m now looking into automatic resizing as the underlying array fills up using calls to realloc. This should make sense to anyone who’s ever used Java or C# StringBuilder…
