Pascal is a programming language named in honor of the French mathematician Blaise Pascal. First appearing in 1970 and officially released in 1973, it was designed to promote good programming practices using structured programming and data structuring. Developed by Niklaus Wirth, Pascal was a direct descendant of ALGOL 60 but had more sophisticated and advanced features. The language gained prominence in teaching computer science due to its emphasis on clear notation for program design. In practicing strong typing, it helps prevent unintended operations from being applied to data types inconsistently, thus catching many errors at compile time instead of runtime. Its main control structures are if-then-else-end if statements, while/repeat-until loops—designed for clarity over brevity—and case statements for multi-way branching.
