The Graphics Interchange Format (GIF) is a digital image format used to store bitmaps. Since it was introduced in 1987, it has been largely used on World Wide Web to allow websites to include images in their pages. It is an efficient format because:• is limited to 8-bit indexed color• it has a good compression […]
Read More →Memory allocation at the applications run-time enables the use of a storage space, expressed in number of bytes, having the size of heap memory required for data storing defined by the variables. Compile-time allocation allows the reservation and use of storage space with predefined size expressed in number of bytes. In this situation, software developers […]
Read More →In C++ programming language, memory areas can be accessed indirectly through pointer type variable […]. Also, available with a memory address, it ensures movement on memory areas from the memory address stored in the variable pointer. This is ensured by arithmetic operators and it is called arithmetic of pointers. Depending on the nature of arithmetic […]
Read More →Areas of heap memory are accessed via variables of pointer type […]. This kind of variable manages values of memory address type. Arithmetic of pointers […] involves the operators use to access the areas of heap memory. Allocating of heap memory areas is done by functions and/or operators implemented in programming language. In the below […]
Read More →The pointer type variables allow the accessing of memory areas with numerical content for the management of the values which represent memory addresses. The dimension of a pointer variable depends on the processor architecture.In the C++ programming language, the definition template of a pointer variable is:
Read More →The usage of the programming elements included in DLL’s […] it is made in C++ applications by respecting the rules stated below.The usage of a DLL in the C++ programming language in the Visual Studio programming environment, it is made in the following way: Create a C++ project – type: Console application; Define the content […]
Read More →The storage structures for sparse matrixes are presented at […].The simply linked list is a linear data structure, formed by elements called nodes. A node is composed by two categories of fields: The field with the information necessary for processing; The field with the information for connecting with the successor node in the simply linked […]
Read More →The sparse matrix represents a special type of two-dimensional array consisting of a large number of elements from out of which a very high proportion is occupied by null elements. Thus, the classical declaration of a two-dimensional array in the C++ programming language leads to unnecessary use of memory by storing null values and of […]
