High-Level Computer Languages

• A computer language that closely mimics “natural language” (as suppose to 0 and 1)
• High-level languages provide high abstraction to the CPU Instructions

• A program that “translates” a High Level Language into Low Level Language (like machine language) is called a compiler

Compilers

Compilers are…

• Language-specific
  • Compiler for Python will not work for C++, etc…
• Linux/UNIX OS have different built-in compilers
  • e.g. g++ for C++, clang for C, etc…

In here, Source code is the original program in a high level language (text file)

and Object code is The translated version in machine language (binary file)

C++ Language

• invented in 1980s
• based on The C Language
• It’s the top-3 of most used today with Python and Java

And a sample program might look like this:
