Introduction to Programming
Exam Materials
Course Introduction
Introduction to Programming provides students with foundational knowledge and practical skills for writing computer programs. The course introduces core programming concepts such as variables, data types, control structures (such as loops and conditionals), functions, and basic data structures. Through hands-on exercises and projects, students learn to solve problems methodically and develop logical thinking. Emphasis is placed on writing clear, well-documented code and understanding how software is created, debugged, and maintained. By the end of the course, students will be able to design, implement, and test simple programs using a contemporary programming language.

Sample Questions
Q1) Parentheses - may contain data to be sent to the method, but may be empty if no outside data is required
Answer: The predictRaise method calls the calculateBonus() method. However, you do not know how the calculateBonus() method actually works. You only know that it accepts a double as a parameter (because newAmount is passed into it) and that it must return either a double or a type that can automatically be promoted to a double. In this way, the method acts as a black box.
Q2) When a variable ceases to exist at the end of a method, programmers say the variable ____.
A) is undeclared
B) is out of memory range
C) goes out of scope
D) is lost
Answer: C
