C does not have stream pointers.
In C++, seekg is a method/function of the standard fstream library (fstream::seekg()) which allows you to position the 'get' pointer to an arbitrary position within the stream.
Increment or decrement the pointer by the required offset.
It is a pointer that points to a member of a structure.
no
the purpose of pointer in c for saving the memory space.,and reduce the length and complexity of the program
Pointer in C is Memory Reference. It stores memory address of any variable, constant, function or something you later use in your programming. Pointer basically used to ease the referencing of variables and others or in polymorphism and inheritance.
The pointer that points to a block of memory that does not exist is called a dazzling pointer or wild pointer
int* pint; // instantiate a pointer to an int. float* pflt; // instantiate a pointer to a float.
Pointer is a variable, A variable that stores the address of another variable. Size of a pointer is 2 bytes.
Double (**) is used to denote the double pointer. As we know the pointer stores the address of variable, Double pointer stores the address of any pointer variable. Declaration : int **ptr2Ptr;
void pointer
Usable. A prominent example is param argv of function main.
