Exploring Programming Languages
The 1970s was a very outstanding year for programming languages. The five most popular languages of the decade where Ada, Pascal, C, Smalltalk, and bliss. The creators of the languages are as follow: Ada-Jean Ichbiah at Alsys in the 1970s primarily for applications used by the U.S. department of Defense. The program is named in honor of countess Ada Lovelace, an influential and historical figure in the field of computing. Pascal-Niklaus Wirth and Kathleen Jensen in the 1970s and was originally designed for teaching programming. C-Dennis Ritchie in 1972 at Bell Laboratories, which is a very powerful and yet general purpose language. Smalltalk-Daniel Henry Holmes Ingalls, Jr. it was created in 1972 as the language to underpin the new world of computing and in part for education. BLISS-W.A. Wulf and D.B. Russell back in 1970 at
