Need for Memory Management operators The concept of arrays has a block of memory reserved. The disadvantage with the concept of arrays is that the programmer must know, while programming, the size of memory to be allocated in addition to the array size remaining constant. In programming there may be scenarios where programmers may not know the memory needed until run time. In this case, the programmer can opt to reserve as much memory as possible, assigning the maximum memory space needed to tackle this situation. This would result in… Read More

In this C++ tutorial, you will learn about two interesting types of pointers; void pointers and Null Pointer. These pointers will be discussed in conjunction with syntax, usage and example. Pointer to Void General Syntax: void* pointer_variable; Void is used as a keyword. Referring back to pointer definitions and usage, it is known that the data type the pointer variable defines is the same as the data type the pointer points to. The address placed in a pointer must have the same type as the pointer. For example: int i;… Read More
