C++ Datatypes Tutorial
A tutorial that tells about datatypes available in C++
C++ practically offers most of the necessary data types except for a basic data type string. This is a big trouble in C++ without such a good feature. Anyway, this c++ tutorial will discuss the basic data types necessary for C++ ...
C++ Array Tutorial
A tutorial that tells about Arrays and what's its importance in C++
C++ Arrays are the data structures which can be used to store consecutive values of the same data types. C++ Arrays can be declared for all c++ data types viz., int, float, double, char, struct, char etc., All the values are stored in consecutive memory locations. The values can be accessed by using the position of the stored value ...
C++ Class Tutorial
A tutorial that tells about class & how it can be created
A class in C++ is an encapsulation of data members and functions that manipulate the data. The class can also have some other important members which are architecturally important ...
Function Overloading Tutorial
A tutorial that tells about function overloading and how this concept is useful in creating C++ programs
Function overloading is the practice of declaring the same function with different signatures. The same function name will be used with different number of parameters and parameters of different type. But overloading of functions with different return types are not allowed ...
Static Functions Tutorial
A tutorial that talks about static functions and how it differs from normal functions
Static data types can be accessed without instantiation of the class in C++. This is applicable for static functions also ...
File I/O Tutorial
A tutorial that shows how to use File I/O classes and functions
File handling is an important part of all programs. Most of the applications will have their own features to save some data to the local disk and read data from the disk again. C++ File I/O classes simplify such file read/write operations for the programmer by providing easier to use classes...
Class Templates Tutorial
A tutorial that shows how to create class templates in C++
C++ Class Templates are used where we have multiple copies of code for different data types with the same logic. If a set of functions or classes have the same functionality for different data types, they becomes good candidates for being written as Templates ...
Overloading Operators Tutorial
A tutorial that explains the basics of operator overloading in c++
C++ overloading is the mechanism by which the language standard operators are used for customized operations of the classes. For example if we are trying to write a string class, we would very simply ask for "+" operator to handle string concatenation, "-" for removing one part of string from another etc ...
Dynamic Memory Allocation Tutorial
A tutorial that explains the fundamentals of memory allocation in a C++ program
So you have just finished your program and you would like to see it at work. Usually you press a combination of keys to compile and run it. But what actually happens when you press those keys ? The compilation process translates your code from C++ to machine language, which is the only language computers "understand". Then your application is given a certain amount of memory to use, which is divided into three segments as follows ...
Memory Leaks Tutorial
A tutorial that explains how a memory leak happens and gives some tips on how to avoid it
A memory leak is what happens when you forget to free a block of memory allocated with the new operator or when you make it impossible to do so. As a consequence your application may eventually run out of memory and may even cause the system to crash. I will now give you a few tips. Remember that code lines shown in red are the best alternative to each situation - they may be added or may even replace previous code ...
