Use a ref local to store a managed pointer in C# You can also use a ref local to store a managed pointer. The following code snippet illustrates how this can be achieved. Note the use of the ref keyword on both sides of the assignment. public static void UpdateDataUsingRefLocal(MyStruct...
A multi-level pointer is essentially a pointer that points to another pointer. Consider a regular pointerint *pwhich points to an integer. A pointer to this pointer would be declared asint **pp, and it holds the address ofp. Multi-level pointers are used in scenarios like dynamically allocate...
our pointer MYPOINT contains the address 0x2000. This is the address of MYEXAMPLE so we say MYPOINT points to MYEXAMPLE. So there is the pointer and the value pointed to. (You can use a pointer in a certain way to get the value at the address to which the pointer points). Many no...
The solution to the above problem is Smart Pointers. Smart pointers automatically handle many of these problems. They are basically an object which behave like pointers i.e. wrap a bare pointer but provides extra functionality. So we should use these in place of bare pointers. Now, let us u...
Use &var Notation to Get the Address of a Given Variable In C, a pointer is a variable that holds the memory address of another variable. To declare a pointer, we can use the type *var notation, where type represents the data type of the variable the pointer will point to. The pointe...
//declaration of function pointer int(* pfAddTwoNumber)(int, int); Now its time to initialize the function pointer with function address. There is two way to initialize the function pointer with function address. You can use the address-of operator ( &) with function name or you can use ...
PointerIn C language, it is difficult to use the pointer to access the two-dimensional array element. The reason is the addresses of two-dimensional array are many, pointers that can access the two-dimensional array element are many and complex. This paper analyzes the two-dimensional array ...

fputc() in C writes the character (unsigned char) to the output stream, at the specified position and then advances the indicator appropriately.
