Algol 60 is a programming language developed in the 1960s, known for its clear structure and powerful features. It was designed to facilitate scientific and mathematical computations, making it easier for programmers to express complex algorithms. Its syntax introduced concepts like block structure and nested functions, which influenced many later languages. One of the key contributions of Algol 60 was its role in the development of programming language theory. It served as a foundation for many subsequent languages, including Pascal and C. Its emphasis on readability and precision helped shape modern programming practices, making it a significant milestone in computer science history.
