This guide explores two critical types of programming errors: syntax and logical errors. Syntax errors occur when the format of an instruction is incorrect, preventing the compiler from creating an executable. Conversely, logical errors stem from mistakes in the program's logic, leading to incorrect output or early termination. These errors can be elusive and the hardest to trace, often identified by the development environment. Understanding these concepts is essential for programmers to write effective and error-free code.

Error Types • SYNTAX: • Format of instruction is incorrect • Compiler will not create an executable • Error may be indentified by the compiler development environment • LOGICAL: • Programming (programmer) error • Program may run – output is incorrect • Program may “blow off” (abend/terminate) early • Most difficult error to locate
