Features of Programming Languages and Algorithm for Calculating the Effectiveness

The article provides information on the basics of software engineering, programming and programming languages. Software engineering is also defined as a systematic approach to the analysis, scheduling, design, evaluation, implementation, testing, service and software upgrading. Thinking and the peculiarities of the algorithmic peculiarities are clarified, and the mechanism of their use in programming is explained. Programming theory incorporates the formal methods based on software specifications and the method based on the mathematical subjects and provides program development using mathematical symbols and ensures the accuracy to obtain the required results on the computer. The principles of using graphs in programming and dynamic programming are analyzed. The concepts of programming technology and programming languages ​​are described. The criteria for evaluating the programming languages ​​are identified and an algorithm is developed for calculating the effectiveness

Means of Expression of Temporal Deixis by Demonstrative Pronouns in the English Language

The article has been written on the basis of synchronic descriptive method in the study of the English language. It explores some ways of expressing the temporal deixis by means of demonstrative pronouns in the English language. It is noted in the article that demonstrative pronouns in the English language do not have any temporal meaning. The temporal meaning appears in the English language only in combination with nouns which denote time. In the English language temporal deixis is realized in the system of demonstration with the help of word combinations: this + noun, that + noun. The above mentioned word combinations fulfil anaphoric and cataphoric functions and can take different positions in the sentence. The article also covers discussion of linguistic views of scientists in this field. We think that urgency of the work just lies in the theoretical problems discussed in the article. The article is also of both theoretical and practical importance in the view of learning English and developing the science of linguistics as a whole
