Introduction to C++

ð Introduction to C++

C++, as we all know is an extension to C language and was developed by Bjarne stroustrup at bell labs. C++ is an intermediate level language, as it comprises a confirmation of both high level and low level language features. C++ is a statically typed, free form, multiparadigam, compiled general-purpose language.

Introduction to Pointers

Pointers are variables that hold address of another variable of same data type.

Pointers are one of the most distinct and exciting features of C language. It provides power and flexibility to the language. Although pointer may appear little confusing and complicated in the beginning, but trust me its a powerful tool and handy to use once its mastered.

Types of Function calls in C

Functions are called by their names. If the function is without argument, it can be called directly using its name. But for functions with arguments, we have two ways to call them,

1. Call by Value

2. Call by Reference

Functions in c

A function is a block of code that performs a particular task. There are times when we need to write a particular block of code for more than once in our program. This may lead to bugs and irritation for the programmer. C language provides an approach in which you need to declare and define a group of statements once and that can be called and used whenever required. This saves both time and space.

C functions can be classified into two categories,

1. Library functions
2. User-defined functions
