Prolog read input
WebProlog or PROgramming in LOGics is a logical and declarative programming language. It is one major example of the fourth generation language that supports the declarative programming paradigm. This is particularly suitable for programs that involve symbolicor non-numeric computation. WebOn the basis of the Prolog version, there may be incompatibility for the input of character between reading the end of record from a file and from a terminal of the user. At the user's terminal, the end of a line of input will be indicated using the character with 13 ASCII value.

After a program is consulted, you can ask queries about the predicates it defines. biography hugh grantSo far we have seen that we can write a program and the query on the console to execute. In some cases, we print something on the console, that are written in our prolog code. So here we will see that writing and reading tasks in more detail using prolog. So this will be the input and output handling techniques. See more In this section, we will see how we can use files to read from, and write into the files. There are some built-in predicates, that can be used to read from file and write into it. See more We have seen how to read specific contents (few lines) of a file.
