Functions
A function is a group of statements that together perform a task. Every C++ program has at least one function, which is main(), and all the most trivial programs can define additional functions. You can divide up your code into separate functions. How you divide up your code among different functions is up to you, but…

String Concatenation
String concatenation is the process of adding an element to an existing element. In this context, string concatenation is the method by which two (or more) strings can be added to one another. Hence, the resultant string is the combination of the initial string and the added string. There are several methods to concatenate strings…

String Length
Length of a string is the number of characters present in the string. These characters can be of the data type char, and these include all alphanumeric elements, symbols and miscellaneous characters. In C++ programming language, there are two types of strings- Character Arrays of C-Style type, and String objects which are built-in objects of <string> class. The length of a string also includes…

Strings
C++ provides following two types of string representations − The C-Style Character String The C-style character string originated within the C language and continues to be supported within C++. This string is actually a one-dimensional array of characters which is terminated by a null character ‘\0’. Thus a null-terminated string contains the characters that comprise the string…

Structures (struct)
C/C++ arrays allow you to define variables that combine several data items of the same kind, but structure is another user defined data type which allows you to combine data items of different kinds. Structures are used to represent a record, suppose you want to keep track of your books in a library. You might want to…

Date and Time
The C++ standard library does not provide a proper date type. C++ inherits the structs and functions for date and time manipulation from C. To access date and time related functions and structures, you would need to include <ctime> header file in your C++ program. There are four time-related types: clock_t, time_t, size_t, and tm. The types – clock_t,…

References
A reference variable is an alias, that is, another name for an already existing variable. Once a reference is initialized with a variable, either the variable name or the reference name may be used to refer to the variable. References vs Pointers References are often confused with pointers but three major differences between references and…

Pointers
C++ pointers are easy and fun to learn. Some C++ tasks are performed more easily with pointers, and other C++ tasks, such as dynamic memory allocation, cannot be performed without them. As you know every variable is a memory location and every memory location has its address defined which can be accessed using ampersand (&)…

Arrays
C++ array stores a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type. Instead of declaring individual variables, such as number0, number1, …, and number99, you declare…
