In C++, the cumulative sum, also known as the prefix sum of an array is the sum of all elements of the array at the current index including the sum of the previous element...read more

In C/C++, arrays can be allocated in two areas of memory: the stack and the heap. Each has its own characteristics and use cases. In this article, we will see the key diff...read more

C-Dynamic Memory Allocation

In C++, a deque (double-ended queue) is a data structure that allows insertion and deletion at both ends whereas arrays are fixed-size collections of elements. In this art...read more

In C++, an array is a fixed-size linear data structure that stores a collection of elements of the same type in contiguous memory locations. In this article, we will learn...read more

C++ Array Programs

In C++, an array is a data structure that stores elements of similar type in contiguous memory locations. We can access the elements of an array using array indexing. In t...read more

In C++, dynamic memory allocation allows us to allocate memory during runtime. Dynamic allocation in an array is particularly useful when the size of an array is not known...read more

C++ Array Programs

In C++, arrays are linear data structures that can store data of the same type in contiguous memory locations. In this article, we will learn how to compare two arrays to ...read more

In C++, an array of arrays is called a 2D array, or two-dimensional array. Deallocating a 2D array means freeing the allocated memory to prevent any memory s, especial...read more

In C++, arrays are static data structures with a fixed size, hence directly adding new elements at the front or middle is not supported in C++ like any other dynamic data ...read more

C++ Array Programs

In C++, a character array is treated as a sequence of characters also known as a string. Converting a character array into an integer is a common task that can be performe...read more

In C++, pointers and array notations are two ways using which we work with arrays and memory for accessing the data. They have distinct behaviours and are used in differen...read more

A deck of cards is a collection of 52 playing cards in which each card is uniquely identified by its suit and rank, there are four suits: heart, diamond, club and spade ea...read more

C++ Array Programs

C++ provides a fixed-size sequence container named std::array. It is a useful alternative to C-style arrays, providing additional features such as bounds checking and iter...read more

In C++, both iterators and array indices are used to access and manipulate elements in a container, such as arrays, vectors, and lists. However, one common question that a...read more

In C++, std::vector is a dynamic array provided by the Standard Template Library (STL), and it is commonly compared to plain arrays. A frequent question that arises is: Is...read more
