What is the difference between structure and pointer?
A structure is a collection of primitives or other structures. A pointer is a memory address. Comparison of the two is like comparing bowling balls to cinder blocks. You can say that a structure defines the layout of the data, while a pointer points to data that is a particular structure.
What is difference between the arrow and the dot operator in c structures?
The arrow is used when a pointer variable is used to get at a member of a structure, and the dot operator is used when dealing with the real structure.ptr->fld == (*ptr).fldstr.fld == (&str)->fld
What is the difference between a function pointer and a pointer to a function?
A pointer to a function is the memory address that stores the address of a function, while the pointer itself is a function pointer.A pointer to a function might be defined as "int (*pf)(int, int);", while to actually point to the function, you would use a function pointer, such as "pf = &func;".
Difference between program counter and instruction pointer?
There isn't any difference. Two different words forexactly same thing. Third way to call it is instruction address register.
What is the difference between Typedef and Reference in C plus plus?
A typedef is a compiler macro. A reference is a pointer, usually implemented with transparent syntax. They have no relationship between each other.

Difference between pointer to constant and constant pointer?
1. pointer to a constant means you can not change what the pointer points to 2. constant pointer means you can not change the pointer.
Difference between genric pointer and normal pointer?
Generic pointer of type 'void *' is compatible with any (data-)pointer, but you cannot use the following operators on it: + - ++ -- += -= * -> []
Give the difference between function and pointer in c?

Difference between void pointer and null pointer?
A Null pointer has the value 0. void pointer is a generic pointer introduced by ANSI. Before ANSI, char pointers are used as generic pointer. Generic pointer can hold the address of any data type. Pointers point to a memory address, and data can be stored at that address.
What is the difference between a function pointer and a pointer to a function?
A pointer to a function is the memory address that stores the address of a function, while the pointer itself is a function pointer.A pointer to a function might be defined as "int (*pf)(int, int);", while to actually point to the function, you would use a function pointer, such as "pf = &func;".
Difference between gui and non-gui modems?

How accessing a pointer an a variable differs?
Pointer-variables are variables, so there is no difference.
What is the difference between instruction registers and instruction pointer?
instruction register is used to store the next instruction to be executed. instruction pointer is used to store the address of the next instruction to be executed.
