Word processing India’s experts use Computer and special software to write, edit, print, format, and save text. In addition to these basic abilities, the latest word processors enable users to perform a variety of superior functions. Although the superior features vary among many word processing applications, most of the latest software facilitates the exchange of information between different computer applications, allows easy access to the World Wide Web for page editing and linking, and enables group of writers to work together on a common project for word processing Writing is talented by using the computer’s typewriter, Keyboard. Characters appear on the computer screen as they are typed. A finite number of characters can be typed across the computer screen. The word processor “knows” when the user has reached this limit and automatically moves the cursor to the next line for uninterrupted typing.

C++ Programmer? Do you need to parse mathematical expressions in C++? bcParserCPP Mathematical Expression Parser for C++ parses and evaluates math expressions given as strings at runtime.

Parsing formulas given as strings at runtime is a challenge for any programmer when he wants to allow the user input a mathematical formula. It is easy to compute mathematical expressions that are known at compile time. We type it in our C++ code, compile and when we execute our program, we get the result. For example x+sin(x) can be easily computed when the value of x is supplied. However, when the mathematical expression is given as a string at runtime, for example “x+sin(x)”, it is no different then a meaningless “abc”. The programmer has to make an explicit effort to make the program understand that there is a plus (+) sign that adds the value of x and the value of sin(x). Of crourse, the program also needs to understand the concept of a function call such as “sin(x)”.

The concept of breaking such an expression into it’s conceptual sub-sections is called parsing. The programmer writes code which typically creates a data structure which represents the mathematical expression in a way that can be used to evaluate it efficiently. This is a simplified, very high level, birds eye view of the solution process.
