Computer Numbering Systems

• Decimal: Base 10, uses digits 0-9, Example: 240
• Binary: Base 2, uses digits 0 and 1, Example: 11110000
• Hexadecimal: Base 16, uses digits 0-9 and letters A-F, Example: 0x7F

1 Byte of Memory

• 1 byte = 8 bits = 2 hexadecimal digits
• Decimal: 0 to 255
• Binary: 00000000 to 11111111
• Hexadecimal: 0x00 to 0xFF

Computer Architecture

• Input (Take input)
• Process (Process information)
• Storage (Store information)
• Output (Output results)

Converting Numbering Systems

• Example conversion from decimal to binary, binary to decimal and hexadecimal, and hexadecimal to decimal.

Converting 243 Decimal to Binary

• Show step-by-step calculations

Converting Hexadecimal to Decimal

• Show step-by-step calculations

C++ Coding

• General guidelines for coding practice style.

Additional Resources

• Khan Academy lessons (digital information, computers): Provide specific links
• Additional tutorials or documents for help: Supply links

Problem Solving

• Solve 2 coding problems, don't look at the solutions until after attempt
• Complete 5 practice questions in a self-assessment

Problem: Converting Fahrenheit to Celsius

• Identify the inputs (Fahrenheit)
• Identify the outputs (Celsius)
• Create examples (e.g., Fahrenheit: 32, Output Celsius:)

Problem #1: Fair Pass Cost

• A single fair ticket costs $8.
• A family pass costs $25 more than half of the ticket.
• Calculate the cost of the family pass.

History of C++

• 1979: C with Classes
• 1985: First commercially released version of C++
• 1998: ISO/ANSI C++98 First standardization
• 2011: ISO/ANSI C++11
• 2014: ISO/ANSI C++14
• 2017: ISO/ANSI C++17
• 2020: ISO/ANSI C++20
• 2023: Next major revision

Development Considerations

• Initial Development: Programming language, Clarity of Design, Programming Time, Debugging/Testing Time, Speed of Execution, Size of program and data
• Maintenance: Flexibility, expandability, portability, clarity of code, documentation

Coding Standards in C++

• Use of comments, appropriate coding style, namespace usage guidelines

C++ Rules and Standards

• C++ symbols like { }
• main function
• case-sensitivity
• data types, and other essential coding rules.

Comments

• Comments are documentation
• Do NOT re-state the instruction, describe the meaning and algorithm.

C++ Program

• Include - Input / output
• int main () {
• Display Hello World and C++ message
• Return 0

C++ Program Execution Process

• Different steps involving the editor, preprocessor, compiler, linker

Pre-work Grade

• Post weekly discussion questions
• Complete week 02 module in D2L 100%

Help / Office Hours

• Student office hours, by appointment and drop-in via Zoom
• Email address for questions
• On-campus tutoring information
• 24/7 online tutoring through D2L

This quiz covers the fundamental concepts of computer systems and problem solving as outlined in Week 01 of CSC 1060. Topics include digital information, computer numbering systems, and an introduction to C++. Test your knowledge on ASCII, C++ program execution, and the history of C++.
