The course is designed to teach the basics of programming. The basic concepts of programming - algorithm, performer, algorithmic language, variable, basic data types, control structures of algorithmic language, etc. p. General methods of programming based on the application of mathematics, such as the calculation of functions on sequences by applying the theory of inductive functions and the scheme of constructing a cycle by means of an invariant . are presented. The general principles of the device and the operation of the computer, typical processor commands and registers, addressing methods, methods of calling functions and transmitting parameters, etc. p. Examples of program recording are given both on the virtual RTL Assembly and on the Intel 80386 processor Assembly. Multitasking Support Hardware Briefly Reviewed. A significant part of the course is devoted to the basics of the C language . In addition to the basics of the language, it provides many examples of the implementation of algorithms in C, such as calculating the root of the function, bringing the matrix to a stepwise view by the Gaussian method, working with files and texts, etc. p. Recent lectures on data structures and their implementations. Sequential and direct access structures such as stack, queue, list, tree, set, and loaded set, as well as their continuous and reference implementations. are considered. A significant place is given to the implementations of the set using binary search, based on balanced trees and using the hash function. The course is useful for students and teachers of universities .
