CHAPTER 15
True/False
l. A computer program is a set of instructions that directs a computer to perform tasks.
2. In the design programs step, the programmer writes the actual program instruction.
3. The program specification package identify the input, output, processing, and data
requirements of each program.
4. The selection structure, means one or more processes continue to occur as long as a given
condition is met.
5. The sequence control structure, gives programmers a way to represent conditional program
logic.
6. Dead code is any code, or program instruction, that a program never executes.
7. Syntax errors are identified by the computer when it executes the program instructions.
8. Program errors are sometimes called bugs.
9. Programs written in all other languages are eventually converted into assembly language.
10. Third-generation languages cannot be read by programmers and are thus more difficult to
learn and use than machine or assembly languages.
11. Fourth-generation languages are nonprocedural and can be used by individuals with very
little programming background.
12. Cobol is difficult to write and read, but it is a succinct language that produces very short
program code.
13. BASIC is an abbreviation for Basic All-purpose Symbolic Integrated Computer.
