How does programming language evolve

Further, it was recognized that the closer the syntax, rules, and mnemonics of the programming language could be to natural language the less likely it became that the programmer would inadvertently introduce errors called bugs into the program.

Hence, in the mids a third generation of languages came into use. These algorithmic, or procedural, languages are designed for solving a particular type of problem. Unlike machine or symbolic languages, they vary little between computers. They must be translated into machine code by a program called a compiler or interpreter. Early computers were used almost exclusively by scientists, and the first high-level language, Fortran [ For mula tran slation], was developed —57 for scientific and engineering applications by John Backus at the IBM Corp.

But do you know that Programming Languages are having a long and rich history of their evolution? It was Ada Lovelace who has written the first-ever computer programming language and the year was In the early days, Charles Babbage had made the device, but he was confused about how to give instructions to the machine, and then Ada Lovelace wrote the instructions for the analytical engine. First time in history that the capability of computer devices was judged.

Skip to content. Change Language. These capabilities constitute the machine language of the computer. But because this language is so far away from the way people think and want to describe solutions to problems, so-called high-level programming languages have been conceived.

These languages use less primitive notations than machine language and hence they require a program which will interpret their meaning to the computer. The purpose of this book is to study how these programming languages are designed to meet the needs of the human and the machine. Unable to display preview.
