Object-Oriented Data Structures in C++: University of Illinois at Urbana-Champaign. Deleting a single variable. When we are done with a dynamically allocated variable, we need to explicitly tell C++ to free the memory for reuse. For single variables, this is done via the scalar (non-array) form of the delete operator: delete ptr; ptr = nullptr;Header guards do not prevent a header from being included once into different code files. Note that the goal of header guards is to prevent a code file from receiving more than one copy of a guarded header. By design, header guards do not prevent a given header file from being included (once) into separate code files.

In most cases, C++ will allow us to convert values of one fundamental type to another fundamental type. The process of converting a value from one type to another type is called type conversion. Thus, the int argument 5 will be converted to double value 5.0 and then copied into parameter x. The print () function will print this value, resulting ...
