PrefacePREFACE C++ is a programming language that introduces object-oriented mechanisms based on C. C++ inherits most features of C. On one hand, C++ treats C as its subset, allowing compatibility with C; on the other hand, C++ supports object-oriented programming, such as the concept and properties of classes. This is a significant improvement over C. … Read more

C++ programs can be defined as a collection of objects that interact with each other by calling their methods. Objects Objects have states and behaviors. For example: a dog’s state – color, name, breed; behavior – wagging, barking, eating. Objects are instances of classes. Classes Classes can be defined as templates/blueprints that describe the behaviors/states … Read more
When programming with a programming language, various variables are needed to store different types of information. A variable retains the memory location of the value it stores. This means that when a variable is created, some space is reserved in memory.Various data types (such as character, wide character, integer, floating-point, double floating-point, boolean, etc.) may … Read more
