Study Notes
Types of Program Translators
- Compiler: translates the entire program into machine language at once, giving a list of errors
- Interpreter: translates each statement into machine language, line by line, and stops at each error
Categories of Programming
- Systems Programming: writes programs for basic internal functions and specialized functions, e.g., operating systems, device drivers, and utility programs
- Applications Programming: develops programs for specific applications, e.g., business or academic applications
Stages in Applications Programming Process
- Problem Statement: begins with a clear, written statement of the problem to be solved
- Algorithm Development: develops program logic to accomplish the task
- Program Coding: converts program logic into specific syntax of the programming language
- Program Testing: checks the coded program for errors
- Program Documentation: documents the program (optional)
Problem Solving
- Problem Statement: clearly states the problem to be solved
- Algorithm Development: develops a logical sequence of steps to accomplish the task
- Steps to define a problem:
- Restate the problem
- Analyze the problem
- Identify the output (desired result)
- Identify the input (needed data/variables)
- Identify the process (algorithm)
Common Programming Errors
- Syntax Error: occurs when code violates grammar rules and is detected by the compiler
Learn about the differences between compilers and interpreters. Understand how compilers translate an entire program into machine language at once, while interpreters translate programming statements interactively. Explore the advantages and disadvantages of each approach.
