If you're not prepared to be wrong, you'll never come up with anything original. – Sir Ken Robinson
CISS-110 Project 1 The goal of the first project is to become acquainted with your integrated development environment (IDE). This is intended to purposefully introduce errors that you will then correct – preferably one at a time. The reason is that you should experience how some errors may change or completely disappear as a result … Read More “CISS-110 Project 1” »
(Updated November 19, 2024) Short-Circuit Evaluation – Advanced Example The Problem As we know, with the conditional operators && (and) and || (or), we can join multiple Boolean expressions together to form a more complex expression. You may also recall that these operators operate in a mode known as short-circuit. This means that once truth … Read More “Short-Circuit Evaluation – Advanced Example” »

(Updated August 26, 2020) Overview As we write programs we gain knowledge. This is especially true in an educational environment. We learn when to select certain constructs in favor of others. We may also learn about scalability, execution time, memory consumption and I/O utilization. If we are truly blessed, our instructor even explains in detail … Read More “Big-O Notation” »
When designing a basic application program, certain details may be elusive. For example, how many variables will be needed, or how many methods will need to be created. There is no simple prescription that can handle all of the possibilities. The only thing that can be done is begin to process the information and formulate … Read More “Approaching a Project” »
