Now that we have covered the variables and data types it becomes possible to introduce operators. Operators are special symbols that are used to represent and direct simple computations, this is significative importance in programming, since they serve to define, in a very direct...

Dynamic Allocation | Notation -- The arrow operator


To de-allocate dynamic memory, we use the delete operator.

Dynamic Allocation


Dynamic Memory Allocation. We can dynamically allocate storage space while the program is running, but we cannot create new variable names "on the fly".

To allocate a single variable dynamically, we use the scalar (non-array) form of the new operator

Dynamic allocation in C/C++ - C++ Forum


It is accomplished by two functions (in C) and two operators (in C++): malloc and free, new and

Dynamic Memory - New Operator - One, Two and Three dimensional...


When you use dynamic allocation, all the created variables are stored into heap, Heap memory is not managed automatically.

Pointers to objects | Objects containing dynamic members


? members can be accessed using pointers: (*obp).setd(5); ? parentheses around (*obp) are needed because dot-operator has higher priority than dereferencing.

Dynamic Memory Allocation and Deallocation


Dynamic variables are not declared with ordinary variable declarations; they are explicitly allocated and deallocated at run time. Memory allocation is accomplished using the new operator and deallocation is accomplished using the delete operator.

C++ Dynamic Memory


You can allocate memory at run time within the heap for the variable of a given type using a special operator in C++ which returns the address of the space allocated.
