AP Computer Science Principles Premium, 2023: 6 Practice Tests + Comprehensive Review + Online Practice (Barron's Test Prep)

The first step in programming is planning and identifying programmer and user concerns that can affect the solution. Consultation and communication with program users are important aspects of program development to solve problems. When designing a large program, an iterative process helps with correctly coding. Checking for errors in small chunks can make isolating errors more efficient. Once a small chunk of the program is error free, it can be combined with already-checked portions of the program to help create a larger, correct program. This process of designing, implementing, testing, debugging, and maintaining programs is repeated until the entire program is ready to be released.
