General Guidelines/Class Rules

• Make-up exams/quizzes require prior professor approval and exceptional circumstances, following university policy for excused absences
• Students cannot leave the classroom once class starts unless it is extremely necessary, otherwise they will be marked as absent
• Strict compliance expected with dress code, and rules on class tardiness and attendance
• Cell phones and e-gadgets must be silenced during class
• Late homework/projects not accepted, honesty and integrity are expected, with academic dishonesty leading to failure

Grading System

• Average of examinations accounts for 30% of final grade
• Average of weekly assessment is worth 70%
• Prelim Grade comprises 70% of weekly assessments (Weeks 1-4) and 30% of Midterm Exam Grade
• Midterm Grade is made up of 70% weekly assessments (Weeks 5-10) and 30% Midterm Exam Grade
• End Term Grade uses 70% weekly assessments (Weeks 11-14) with 40% End Term Exam Grade
• Final Grade calculates to be the average of Prelim Grade, Midterm Grade, as well as End term Grade divided by 3
• Passing grade for the course is 5.0

Learning Guide

• Week 1 topics include: Major Components of a Computer Systems, Overview of Computer System Organization, Data Representation, Binary Operations, Arithmetic Sequential, Boolean Logic
• Upon completion of this Learning Module, one will be able to:
  • Identify the major components of a computer system
  • Describe the Computer System Organization
  • Discuss the Data Representation

Major Components of a Computer System

• A program is a list of instructions for a computer
• A computer's programs are referred to as its software
• Hardware refers to the physical machines making up a computer installation
• Software aids in computer and program tasks
• PCs, workstations, and mainframes are the three main classes of computers
• A PC (personal computer) is relatively small, used by one person
• A workstation acts as a large and far more potent PC
• Mainframes are large computers typically with shared users requiring specialist support
• Network contain multiple connected computers to share information, printers and other resources
• For learning programming, the basic computer configuration is the same across PCs, mainframes, and workstations
• The input device(s), the output device(s), the processor, main memory, as well as the secondary memory are key hardware components in computer systems
• Keyboard and mouse serve as input devices

Software

• Communicate with a computer via the operating system
• An operating system allocates computer resources to tasks
• Common operating systems include UNIX, DOS, Linux, Windows, Macintosh, and VMS
• Input for computer consists of program and data
• Program gives a set of instructions for the computer to perform with some type of processing of the data
• 'Data' broadly means computer information
• When a program runs or executes, the computer follows instructions on the supplied data
• Compilers translate high-level language into a machine language to be understood and executed
• The input of a compiler is called a source program (or source code), and the translated version that is produced is called an object program of object code
• The linker combines the object code for all program pieces, with the object code that the compiler produced
• Charles Babbage designed the first programmable computer, with Ada Augusta often called the first computer programmer

Learning Guide Week 2

• Consists of the following topics, Basics of C++, Structure of a program, Data Types, and Variables
• Upon completion of this Learning Module, one will be able to:
  • Identify the basic program structure of C++
  • Use comments for program readability
  • Differentiate Data types from Variables
  • Use Data types and naming variables properly
  • Identify and differentiate the three(3) types of variables
• Typical first program beginner will write is "Hello World", which simply prints "Hello World" to your computer screen
• "//" - indicates a comment by the programmer for explanation
• "#include " directs preprocessor for input and output operations
• "int main ()" - initializes a function
• Functions are a group of code statements given a name
• main is a special primary function, which executes code within
• "{ and }" opens up and closes the function for definition
• "std::cout << "Hello World!"; - indicates an expression in C++
• std::cout which identifies the standard character output device (usually, this is the computer screen).
• insertion operator (<<), which indicates that what follows is inserted into std::cout.
• ("Hello world!") - is the content inserted the output into the standard output
• (;) Semicolon Character which marks the end of the statement, and is a syntax requirement
• It would be the same meaning or effect if written "int main(){std::cout << "Hello World!"; }
• "//" is a line comment, whereas "/* block comment */" is a block comment that can incorporate multiple lines

Variables And Types

• Includes the explicit qualification such as using declarations
• std namespace all elements can be defined without the use f prefix
• Coding, compiling, as well as executing multiple lines of code, obtains a simple text sentence
• Variables are essential to any form of programming in regard to producing outcomes and saving work
• Can add two numbers at the same time using various variables or memory
• We can now define variable as a portion of memory to store a value
• A valid identifier is a sequence of one or more letters, digits, or underscore characters (_). However cannot begin with a digit.
• The C++ language is a "case sensitive" language
