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
