Functions are the building blocks of any programming language. In C++, a function is a block of code that performs a specific task. Think of it as a mini-program within your main program, designed to execute a particular operation. Functions are like building blocks that help break down complex problems into manageable chunks, making your code more readable and modular.
While grasping the fundamentals of encapsulation is crucial, delving into advanced concepts and patterns elevates code design and maintainability further in C++. In this article, we will explore sophisticated aspects of encapsulation that go beyond the basics and provides you with a deeper understanding of its applications and impact on software development.
Function groups a number of program statements into a unit and gives it a name. This unit can be invoked from other parts of a program. A computer program cannot handle all the tasks by it self. Instead its requests other program like entities – called functions in C – to get its tasks done. A function is a self contained, named block of statements that perform a coherent task of same kind.
