Exercise 4.1
Read and translate the text:
A modern digital computer is simply a device that follows instructions. These instructions tell the computer to perform specific actions such as writing information to the video screen, performing complex computations, or reading data from a floppy disc.
In order to solve a problem using a computer, we must express the solution to the problem in terms of the instructions of the particular computer. A computer program is actually just a list of instructions necessary to solve a specific problem, and the creation of this instruction list is computer programming. Programming is the process of producing a set of instructions for a computer to make it perform a specific task. The task can be anything from the solution to a mathematical problem to the production of a graphics package.
The approach or method that is used to solve the problem is known as an algorithm. For example, if we wish to develop a program that tests if a number is odd or even, then the set of statements which solves the problem becomes the program. The method that is used to test if the number is even or odd is the algorithm. To develop a program, to solve a particular problem, we first express the solution to the problem in terms of an algorithm and develop a program, which implements this algorithm. Then we can proceed to write the instructions necessary to implement the algorithm on a particular computer system. These instructions would be expressed in the statements of a particular computer language, such as BASIC, PASCAL, or .
