The EOF is a special
character, whose ASCII value is 26, which indicates the end of a file in text
mode of file. While writing data to a file, this character is inserted
automatically after the last character in the file to mark the end of file. If
this character is detected at any point in the file, the read function would
return the EOF signal to the program indicating the last point of file. An
attempt to read after EOF might either cause the program to terminate with an
error or result in an infinite loop situation. Thus, the last point of file is
detected using EOF while reading data from file. Without this mark, we can not
detect last character at the file such that it is difficult to find up to what
time the character is to be read while reading data from the file.
Object Oriented Programming Programming paradigm that represents the concept of "objects" that have data fields (attributes that describe the object) and associated procedures known as methods Programming methodology based on objects, instead of just functions and procedures Focuses on data rather than process As individual objects can be modified without affecting other aspects of the program, it is easier for programmers to structure and organize software programs Easier to update and change programs written in object-oriented languages Simula was the first object oriented programming language Eg: C++, Java, etc. Features of OOPS Objects Referred as instance of class Basic run-time entities in an object-oriented system a person, a place, a bank account, a table of data, etc can be an object They occupy space in memory that keeps its state Each object contains data and code to manipulate the data Classes Blue print or prototype which defi
