We will discuss the pointer data types later. Pascal is an imperative and procedural programming language, designed by Niklaus Wirth as a small, efficient language intended to encourage good programming practices using structured programming and data structuring.It is named in honour of the French mathematician, philosopher and physicist Blaise Pascal..
