ALGOL 68 is a programming language developed in the late 1960s as an evolution of the earlier ALGOL language. It was designed to improve upon its predecessors by introducing more advanced features, such as structured programming, strong typing, and a rich set of data types. The language aimed to provide a clear and formal syntax, making it suitable for both academic and practical applications. One of the key contributions of ALGOL 68 was its influence on later programming languages, including Pascal and C. It introduced concepts like user-defined data types and block structure, which have become standard in modern programming. Although it never gained widespread popularity, its design principles continue to impact programming language development today.
