There are people all around us who want to travel and want to see new countries. And every journey is a preparation process ... New countries, new cities to see new cultures to see everyone's dream. The program phase begins; passports, visa transactions, airline tickets, reservations ... We need to know their language to understand them better and understand their culture better. This is the most important resource we can use to communicate with people. To understand the computer, which is one of the most important blessings that technology gives us, we need to speak in its language. We need to know the language of this intelligent technology product in order to express what we want to do to him. There are many languages available at this point. Among these languages, C sharp (C #) is used. C sharp (C #) developed by Microsoft; It is a next generation programming language with ECMA and ISO standards. When called C sharp (C #) programming language, "C # Major" is used, resulting from the interleaving of two "+" symbols. C sharp (C #) has begun to develop with ECMA and ISO standards, but it has adapted to standardization with C sharp (C #) 3.0 and improved for .NET. An important institution that sets international standards for ECMA and ISO software languages. In C programming languages, the "+" symbol is used to increase the integer variable. C sharp (C #) includes C ++, the programming language with a long-standing object-oriented language, and the widely used Java programming language. It provides ease of use for both objects, but it does not shrink your usage space by supplying this language with Java, allowing you to move more easily within the programming area. This is one of the greatest convenience for software developers. All of this, C sharp (C #) is at least 3 times faster than Java programming language, and C ++ is satisfactory enough for you to use. The most important advantage of C sharp (C #), which can be optimized for performance as well as being fast, is to use RAM more efficiently through its own resource management. This feature is mostly based on the Java programming language that it contains.
