Introduction to Numbering Systems
- Humans use decimal (base-10)
- Computers use binary (base-2) due to electronic circuitry (ON/OFF)
- Computers communicate in decimal; programs translate between decimal and binary
Converting Decimal to Binary
- Divide by 2, track remainders until no further division is possible
- Order remainders to form binary equivalent
- Example: 29 in decimal = 11101 in binary
Converting Decimal to Hexadecimal
- Divide by 16, track remainders until no further division is possible
- Order remainders to form hexadecimal equivalent
Converting Binary to Decimal
- Multiply each bit by 2n, where n is the bit's position (starting from 0)
- Sum the results.
- Example: 101011 in binary = 43 in decimal
Converting Binary to Hexadecimal
- Group binary digits into sets of 4
- Convert each set into its hexadecimal equivalent
- Example: 10101110 in binary = (2BB)16 in hexadecimal
Converting Hexadecimal to Decimal
- Multiply each hexadecimal digit by 16n, where n is the digit's position (starting from 0)
- Sum the results
- Example: (ABC)16 = 2748 in decimal
Converting Hexadecimal to Binary
- Convert each hexadecimal digit to its 4-bit binary equivalent
How to Solve Problems
- Define problem clearly (who, what, where, when, how)
- Analyze input, processing, output
- Design algorithms (steps in solving the problem): Flowcharts, Pseudocode (steps).
- Code the algorithm in a programming language
- Test and debug the code to correct errors
Algorithm Development
- Algorithms are step-by-step instructions to solve a problem
- Can be written in different ways (pseudocode, flowcharts)
Flowcharts
- A diagram using shapes to represent specific steps (start, end, process, decision)
- Helps visualize algorithm steps
Pseudocode
- Step-by-step description of an algorithm
- English-like statements easily translated into programming languages
Testing and Debugging
- Testing: Executing the program with sample data to check output
- Debugging: Finding and fixing program errors (e.g., syntax, runtime, logic errors).
