Study Notes
Error Types
- Compiler error: occurs when one brace in a block is left out of the program.
- Runtime error: has its effect at execution time, like when both braces in a block are left out of the program.
Logic Errors
- Fatal logic error: occurs when a program produces incorrect results, often due to incorrect logic or algorithm.
Conditional Operator
- Empty statement: represented in Java as a single semicolon (;).
- operator: can be used in place of an if…else statement.
- Conditional operator (?:): the operand to the left of the ? is a boolean expression.
Control Statements
- switch statement: selects among many different actions based on an expression.
- Iteration statements: used in programming to repeat a set of statements while a condition is true.
- while loop: keyword used to define a loop that will execute zero or more times.
- If the loop-continuation condition in a 'while' statement is initially false, the loop body will not execute.
Control Flow
- goto statement: connects the exit point of one to the entry point of the next.
- Activity diagram: can be used to represent each control statement visually.
Program Structure
- Bohm and Jacopini: demonstrated that programs and goto statements can be replaced with three structured programming constructs: sequence, selection, and iteration.
- Bohm and Jacopini asserted: that sequence, selection, and iteration are sufficient to write all programs.
Sequence Structure
- Key characteristic: executes statements in a predefined order.
Activity Diagrams
- Used in software systems modeling: to visualize the flow of control in a program.
- UML activity diagrams: commonly use symbols such as rectangles, diamonds, and arrows to represent different stages of control flow.

Description
Explore the use of double-selection and multiple-selection statements to choose between different actions based on an expression, as well as iteration statements to perform actions repeatedly while a loop-continuation condition remains true. Test your understanding of these fundamental concepts in programming.
