Errors in Computer Programming

Q#1: What is an error in computer programming? Describe its types.   

Ans: Error:

            Errors are the problems or the faults that occur in the program which cause the program to behave abnormally.

            The most common errors can be generally classified as follows:

i)                    Syntax Error:

Syntax error occurs when the code does not follow the syntax rule of the programming language. They can be mistakes such as misspelled keywords, a missing punctuation character, a missing bracket, or a missing closing parenthesis.

i)                    Run-Time Error:

Errors which occur during program execution (run-time) after successful compilation are called run-time errors. A run-time error occurs when a program is asked to do something that it cannot perform, resulting in a “crash”.

ii)                  Logical Error:

               Logical errors are those which prevent your program from doing what you expect it to do. On compilation and execution of a program, desired output is not obtained when certain input values are given. These type of error which provide incorrect output but appear to be error free are called logical errors.

 Q#1: What is a word processor? Write any three applications of a word processor.  Ans: A word processor is software or a device that allows users to create, edit, and print documents. It enables us to write text, store it electronically, display it on a screen, modify it and print it to hardcopy. Applications of word processing software:  • Creating, editing, saving and printing documents.  • Formatting text, such as font type, bolding, underlining or italicizing.  • Inserting elements from other software, such as illustrations or photographs.  Q#2: Discuss the Margins and Paper Size options in the Page Setup group.  Ans:  • Margins: A margin is the area or space between the main content of a page and the page edges. This button is used to change the margins of the entire document or selected section.  • Paper Size: The size button is used to choose the size of the paper for current section or entire document.  Q#3: Name and describe tw...

CPU Chip  2. RAM slots  3. Parallel ports  4. CPU slots  5. CMOS battery  Q#9: Define ALU and CU.  Ans:   1. Arithmetic and Logic Unit: ALU performs all the actual calculations like arithmetic operations and logical comparisons. Arithmetic operations include addition, subtraction, multiplication and division while logical comparing, selecting and matching of data.  2. Control Unit: Control Unit (CU) is responsible for controlling the transfer of data and instructions among other units of a computer. This unit controls the operations of all parts of the computer but does not car...

Problem Solving Steps

Q1: Describe the steps involved in problem solving.  Ans:  1) Define the problem:  In problem solving process, the first step is defining or identifying the problem. It is the most difficult and the most important of all the steps. During this stage of problem solving, it is important to describe the problem.  2) Generate alternative solutions: For any problem, there are more solutions to it than the one that is thought of first. Postpone the selection of one solution until several problem solving alternative have been proposed.  3) Evaluate and select an alternative:  Many alternative solution to the problem should be generated before final evaluation. A common mistake in problem solving is that alternative are evaluated as they are proposed, sop the first acceptable solution is chosen even if it is not the best solution.  4) Implement and follow up on the solution:  The plan for best solution also include planning on what happens next if somethi...
