In modern programming, data structures and algorithms are the basic components for writing programs. The tasks solved by the computer are expressed only in exceptional cases at the bit level. Typically, the data is represented as letters, numbers, symbols, and other more complex sequences. Even more intricate is the case with algorithms that are used to solve all kinds of problems. In order for the main data structures to be described as accurately as possible, programming languages have been developed, the meaning of which lies in the uniqueness of all proposals.
Virtually all programming languages are provided with tools that can reference any data structures based on the assigned identifier. The constants and variables are the basic quantities. For a programmer, they say a lot, but that's completely useless for a computer. Therefore, the text of the written program is translated into binary code with the help of a compiler. Sometimes the type of these quantities is determined by the compiler, but in some cases it is required to specify the type of each variable that does not change even when the entire program is executed to the end.
It should be said that the data structure is primarily a method of organizing information in computer memory. The algorithm acts as the corresponding procedural element in the program itself. First, an order of actions was devised to solve the simplest tasks, such as multiplying numbers and calculating trigonometric functions. However, at the present time, other algorithms play an important role, which allow finding a given word in the text, sorting and planning any events. Exact mathematical operations perform important tasks in this case.
In many algorithms, data structures can be incredibly complex. In the end, only the right choice of data representation can be the impetus for successful programming. In addition, the performance of the program will depend on this. In fact, there is no general theory of the choice of this or that structure, and it is unlikely that it will ever face the world. There is only one way out, which lies deep in the basic knowledge. Applying them in practice, you can create the largest systems. However, to achieve mastery in this matter can only be after studying the basics.
To date, there is one serious problem in software development, which is that data structures are rapidly evolving and cause certain processing difficulties. Programmers usually use standard component libraries during their work. They help to eliminate a large number of routine operations. All components are thoroughly tested and well described. However, in the case of libraries, there are significant limitations that can significantly reduce their dignity. They include a huge number of components, but the implementation of their processing leaves very few options.
