Assignment Statement

A compiler is a computer program that translates computer code written in one programming language (the source language) into another language (the target language). The name compiler is primarily used for programs that translate source code from a high-level programming language to a lower level language [7]. The three main processes of compilation are lexical analysis, syntax analysis and semantic analysis. A compiler has two components, front-end and back-end. Front-end portion of a compiler has to do to main tasks lexical analysis and syntax analysis. On the lexical analysis, input source code are scanned and tokenized into various tokens [6]. In the system, front-end portion of the compiler, lexical analysis is used. There are many token elements in C++ programming language. In this system, line break token, white space tokens (space and tab) and operators (+,-,*,/,=,+= and so on) are used as token elements for the assignment statements of C++ source program. This system is taken all the assignment statements of C++ program as input. Of course, the extracted assignment statements may be literals or values assignment statement (e.g. x=3; or pi= 3.142;), variable assignment statement (e.g. x=y; or x=z;) and expression assignment statement (e.g. a=b+c; or x=y*z; or a=b*(c+d); and produced symbol table, step by step recognized table by using finite state automata and lexeme table.

AbstractSummaryHere we describe discoal, a coalescent simulator able to generate population samples that include selective sweeps in a feature-rich, flexible manner. discoal can perform simulations conditioning on the fixation of an allele due to drift or either hard or soft selective sweeps—even those occurring a large genetic distance away from the simulated locus. discoal can simulate sweeps with recurrent mutation to the adaptive allele, recombination, and gene conversion, under nonequilibrium demographic histories and without specifying an allele frequency trajectory in advance.Availability and ImplementationAvailability and implementation: discoal is implemented in the C programming language.

C Programming

The article describes various options for speeding up calculations on computer systems. These features are closely related to the architecture of these complexes. The objective of this paper is to provide necessary information when selecting the capability for the speeding process of solving the computation problem. The main features implemented using the following models are described: programming in systems with shared memory, programming in systems with distributed memory, and programming on graphics accelerators (video cards). The basic concept, principles, advantages, and disadvantages of each of the considered programming models are described. All standards for writing programs described in the article can be used both on Linux and Windows operating systems. The required libraries are available and compatible with the C/C++ programming language. The article concludes with recommendations on the use of a particular technology, depending on the type of task to be solved.

Computing Support

In this paper we deal with a method for the determination of numbers in a Pascal triangle that are simultaneously triangular, tetrahedral and pentaedroidni. The collected results, obtained by mathematical analysis, were verified by computer. For this purpose, we used the C# programming language as well as the computer laboratory within our University in order to test the results. The results collected by computer confirmed the accuracy of the results obtained by mathematical analysis.
