In this case, you can’t replace the original value of the variable x within the called function, as you might do with a C-style pointer type. But you can make modifications to the list assigned to x.Similarly, when one variable is assigned to another, it stores a reference, or an ...
One example is when calling a virtual function virtually; the function can’t be inlined because the compiler may not know which function is going to be called. Another example is when calling a function through a pointer to the function rather than using its name. You should strive to ...
The first instruction loads a managed pointer to myRect on the evaluation stack in preparation for initialization. Using the managed pointer, the next instruction (initobj) initializes myRect to all zeroes. Following initialization, myRect, located in local variable slot 0, is loaded on the stac...
If a variable is marked with both volatile and __restrict, the volatile keyword will take precedence when making decisions regarding how to optimize the code. In fact, the compiler can totally ignore restrict, but must respect volatile. The /favor switch might e...
If the address of a variable is taken, the variable better be stored in a location that has an address. A register doesn’t have an address, so it has to be stored in memory whether it’s available or not. All of this might seem to you that current compilers are terrible at register...
The implementation of this header will vary from machine to machine, but the interface it presents is uniform. The type va_list is used to declare a variable that will refer to each argument in turn; in minimal_printf , this variable is called ap , for "argument pointer". The macro ...
Ans:NULL is used to indicate that the pointer doesn’t point to a valid location. Ideally, we should initialize pointers as NULL if we don’t know their value at the time of declaration. Also, we should make a pointer NULL when memory pointed by it is deallocated in the middle of a ...

Every variable in Python is a reference (a pointer) to an object and not the actual value itself. For example, the assignment statement just adds a new reference to the right-hand side. A single object can have many references (variable names). ...
