Modern Programming
Before a computer can be used to solve a given problem, it must first be programmed, that is, prepared for solving the problem by being given a set of instructions, or program. Various programs by which a computer controls aspects of its operation are known as software. The process of software development consists of the following steps:
As you see programming is only the third step in software development process. An algorithm is a finite sequence of well-understood steps that are followed to solve a particular problem or
produce a particular result and a program is an algorithm that has been implemented in a particular programming language. Programs can be written using many different computer languages. Programming languages can be divided into low-level, high-level and special languages.
Exercise 3. Translate the following word combinations. To solve a given problem, to give a set of instructions, to control aspects of computer operation, to be known as software, to define the problem, to decompose the program into sepаrate operations, to develop a necessary flowchart, to debug and test the created program, to gather and verify all documents, software development process, a particular programming language.
Exercise 4. Write English equivalents to the following words and word combinations.
