C++ -> operator
When an element of a structure has to be accessed through pointer, then the → operator is used. It is essential to initialize the pointer before it accesses any structure element. [Read more…] about C++ -> operator
How to Referencing a structure
Structure elements can be referenced by writing the structure variable before the structure element. The structure variable and the structure element are separated by a dot (.) which is called the dot operator. For example [Read more…] about How to Referencing a structure

Array C++ Binary Search.
This method assumes that the set of elements in a list is first arranged in ascending or descending order. The list is initially divided into two parts and the mid point is found. If the number to be searched is less than the value of the element at the mid point, it implies that the given number lies in the first part of the list, otherwise the given number lies in the second part of the list. This is illustrated as follows: [Read more…] about Array C++ Binary Search.
Array C++ Linear Search
The linear search procedure gives the method of finding whether an element is present in a set of elements (array) or not. The given element is compared with each element in the set one by one. The process is repeated until a perfect match is found. The array comprises of unsorted elements. [Read more…] about Array C++ Linear Search
Array C++ Insertion Sort
Insertion Sort is a sorting technique based on the idea of inserting a new element in a set of given elements so that the resulting elements are also in sorted order. Suppose a set of 4 elements A[0], A[l], A[2], A[3] are to be sorted in ascending order. Initially sort A[0]and A[l] in ascending order. If A[l] is less than A[0], interchange their positions. Otherwise the positions of the elements remain the same. Next insert A[2] in the appropriate position so that the resulting array A[0], A[l] and A[2] remain sorted. The process is repeated in this manner. [Read more…] about Array C++ Insertion Sort
Array C++ Selection Sort
In this method, the smallest item in a given series of n elements is found and is placed in the first position. Then the smallest item from the remaining (n-l) elements is found and is placed in the second position and so on. This method requires (n-l) passes for arranging n elements.

Array C++ Bubble sort
In Bubble sort, two consecutive elements in a given list are compared and their positions in the given list (array) are interchanged in ascending or descending order as desired. Consider the following series of numbers, which are to be arranged in ascending or descending order. The series of numbers to be arranged are presented in the form of an array. The input array has the following form: [Read more…] about Array C++ Bubble sort

How to Declaring Array of Structures in c++
An array of structures refers to an array in which each element is of structure type. To declare an array of structures, firstly, a structure is defined and then an array of that structure is declared. The syntax for declaring an array of structures is [Read more…] about How to Declaring Array of Structures in c++
How to Declaring Nested Structures in c++
Like other user defined data types, a structure can also include another structure, as its member, in its definition. A structure defined within another structure is known as a nested structure. [Read more…] about How to Declaring Nested Structures in c++
How to Declaring and Accessing Structure Variables in c++
A structure can be used in a program only if memory is allocated to it. The structure definition informs the compiler about the type and the number of data members in the structures. However, it does not allocate any memory for the structure. To use a structure in a program efficiently, a structure variable needs to be declared. The syntax for declaring a structure variable is [Read more…] about How to Declaring and Accessing Structure Variables in c++
Defining Structures in C++
Like arrays, structures are also used to store a list of data items in a single variable. However, these data items may be of different data types. Structures are used whenever a programmer requires binding the same or different types of related data items together into a single entity. [Read more…] about Defining Structures in C++
Multi-Dimensional Arrays in c++
Multi-dimensional arrays can be described as ‘arrays of arrays’, that is, each element of the array is itself an array. A multi-dimensional array of dimension n is a collection of items that are accessed with the help of n subscript values. [Read more…] about Multi-Dimensional Arrays in c++
Single-Dimensional Arrays in c++
A single-dimensional array is the simplest form of an array that requires only one subscript to access an array element. Like an ordinary variable, an array must have been declared before it is used in the program. The syntax for declaring a single-dimensional array is [Read more…] about Single-Dimensional Arrays in c++
Difference between Structures and Unions
Both the structures and unions are syntactically and functionally same, however, they differ in the way memory is allocated to their members. While declaring structure variables, the different members are stored in different, although, adjacent memory locations whereas different members of a union variable share the same memory location. The amount of memory sufficient to hold the largest member of a union is allocated to a union variable. Thus, a union enables the same block of memory to store variable of one type at one time and of different type at another time. To understand the concept of memory allocation to a union, consider these statements. [Read more…] about Difference between Structures and Unions
