Chapter 1.4, Problem 26STE

Program Plan Intro

Programming mistakes:

• A fault in a program denotes a bug and process of elimination of bugs is termed as debugging.
• A bug denotes an error, failure or fault in a program that may generate improper result.
• The process of fixing bugs is termed as debugging.
• Some of computer systems are able to deter, detect or auto correct different computer bugs during operations.
• The bugs arise from errors made in source code of program.
• The bugs can cause program to freeze computer in terms of processing.

Types of program errors:

• The three main types of program error includes:
  • Syntax errors:
    • The compiler catches certain mistakes and denotes an error message.
    • It denotes violation of syntax of programming language.
    • The compiler issues an error message if syntax is been violated.
    • The compiler sometimes raises a warning message while any unusual programming practices.
  • Run-time errors:
    • It denotes type of error that system detects when a program is run.
    • The system may detect certain run-time errors and displays appropriate error message.
    • It may be an issue with numeric calculations.
  • Logic error:
    • It denotes a mistake in underlying algorithm.
    • It may be an issue while translation of algorithm to program code.
    • It denotes that there is no error in syntax while the result obtained is not as expected by user.
    • These types of errors could be corrected by careful examination of algorithm and translation.
