The history of computer programming languages

The history of computer programming languages is a fascinating journey that spans several decades. Here's a brief overview of key milestones in the evolution of programming languages: 1. Machine Code and Assembly Language (1940s): In the early days of computing, programmers worked directly with machine code, the binary language understood by computers.
