Explanation:
//Program is written in Java programming language
Class RegularPolygon{
int sides = 0;
int length = 0;
}
public void randomize(RegularPolygon polygon){
int randomSides = (int) 10 + (Math.random() * 20);
double randomLength = 5 + (Math.random() * 11);
polygon.sides = randomSides;
polygon.length = randomLength;
}
Answer:
inFile.open("progdata.dat");
Explanation:
This command opens the file which is passed to it as an argument. We are quite used to the C++'s cin and cout functions contained in iostream library for reading and writing data, however, when working will real-life stuff, we find ourselves working with huge data saved as separate files and require our programs to read them, manipulate them and possibly write back to the files... The first operation usually carried out before a file can be read or written to is open
Answer:
1. Classes and objects
2. Inheritance
3. Polymorphism
4. Data hiding/ encapsulation
5. Interfaces.
Explanation:
Classes and objects depict the major component of the OOP (object oriented programming). It explains the object like a ball in a soccer game development.
The inheritance is like the subclass of the object. Data hiding is a stage in oop where the codes or data are hidden from another users.
In the polymorphism stage, the object is given the ability to change to a sub-object, while in the interface stage a function or method signature is defined without implementing it.
