EGR 1400 ACTUAL EXAMS SCRIPT QUESTIONS
AND ANSWERS SURE A+
✔✔machine languages - ✔✔sequences of 1s and 0s
✔✔assembly languages - ✔✔use short words known as
mnemonics to write the program. It must be translated by assembler. It is still
considered low-level languages.
✔✔high-level languages - ✔✔More human readable languages that allow programmers
to create programs without knowing how CPU works. They use keywords that have
special meanings and cannot be used for any purpose other than to write programs.
Modern languages are high-level.
✔✔operators - ✔✔Keywords that represent special program functions such as addition,
subtraction, and multiplication.
✔✔syntax - ✔✔A set of rules that must be strictly followed to write computer-
understandable instructions.
✔✔syntax error - ✔✔A mistake or violation of syntax rules.
✔✔statement - ✔✔Each instruction in a program.
✔✔compiler - ✔✔Translates a high-level language program to a separate machine
program for CPU to read and execute.
✔✔source code - ✔✔The statements a programmer writes in a high-level language.
✔✔compilation - ✔✔translates a text-based source code to binary codes.
, ✔✔interpreter - ✔✔Reads, translates, and executes the instructions of a high-level
language program.
✔✔user interfaces - ✔✔Allow users to interact with the computer. Categories include:
Command line interface (aka console interface) and Graphical user interface (GUI)- now
the most commonly used.
✔✔object - ✔✔A program component. Program objects have properties (or fields) and
methods. Properties are data stored in an object. Methods are the operations an object
can perform.
✔✔controls - ✔✔Objects that are visible in a program GUI. They enhance the
functionality of programs. Examples include: Labels, buttons, and TextBoxes.
✔✔.NET Framework - ✔✔A collection of classes and other codes that can be used to
create programs for Windows operating system. C# is a language supported by the
framework, controls are defined by specialized classes provided by the framework. You
can also write your own class to perform a special task.
✔✔programming development cycle - ✔✔The process of creating a program. Six
phases: Understand the problem and the program's purpose, design the GUI, design
the program's logic, write the code, correct syntax errors, test the program and correct
logic errors.
✔✔Algorithm - ✔✔A step-by-step series of instructions for solving a problem.
✔✔flow chart - ✔✔Graphically depict the logical steps to carry out a task and show how
the steps relate to each other.
✔✔pseudocode - ✔✔Uses English-like phrases with some high-level Computer
Programming Language terms to outline the task.
✔✔namespace - ✔✔A container that holds classes
✔✔class - ✔✔A container that holds methods.
✔✔method - ✔✔a group of one or more programming statements that perform some
operations
✔✔Program.cs file - ✔✔Contains the application's start-up code to be executed when
the application runs.
✔✔Form1.cs - ✔✔Contains code that is associated with the Form1 form.
