As you learn then, such necessity meets enough Often.Operators of input and output of the information If you remember, by consideration of an example of operation of the operator Assignment we have faced necessity to learn result of performance of the program. We have understood, how the information to save (in variables) how to handle (with usage of expressions), but two ??????? Informational process remained out of our attention: reception of the information and its transmission in external in relation to the computer the world. While our programs Can use only the information which is directly in the program text. To learn, what values have at present variables, Also it was not represented possible. Programming in such conditions loses meaning. Interaction of processing devices and storage of the information with an environment (at least with the user) is absolutely necessary. For the such The interface in language of Pascal information input\output statements answer. These instructions allow to enter arguments, parametres of calculations into program execution time (instead of at a stage of its spelling) to carry out output of the calculated data in clear to the person sort. At first input operators (formats of operators): Read (<the input List>); Readln (<the input List>); In such format these commands allow to enter the data into variables in execution time of the program from the keyboard. Names of variables which should be filled by the values entered from the keyboard can be units of the list of input. Performance of operators of input occurs so: a program course ![]()
