PROGRAM CONSTRUCTS

PROGRAM CONSTRUCTS

1. Low level language

   • A language that is very close to binary instructions

2. High level language

   • A language that in which programs are written in a style closer to that of human language

3. Machine Code

   • Binary instructions used by the CPU

4. Assembly Code

   • Low-level language which use mnemonic codes to represent machine code

5. Compiler

   • Converts high level language into machine code at the end of the code

6. Interpreter

   • Converts high level language into machine code line by line

7. Assembler

   • Converts low level assembly code into machine code

8. Types of Errors

   • Syntax
     • When something in the code is grammatically incorrect
   • Run-time
     • This error might occur when the program is running because more memory might be requested when there is none left.
   • Logical
     • When an incorrect output is given out
