Size if a void pointer is equal to the size of a char pointer. Even though they point to the data types of different sizes!!!

All pointers are of the same size. The size of which depends on the machine - 64/32 bits

All pointers are of size 2 bytes...(in turbo C)..

Actually size of a pointer is fixed,it is 1word.Now 1 word is defined in dos as 2 bytes,but in windows it is 4 bytes.

The size of any pointer variable is same. ( 2 byte in case of 32 bit machine ).

The type of pointer defines the type of data the pointer is pointing to .

eg. if the pointer is definde as

int *p;

then it will create a pointer p ( of two bytes ) which is pointing to a data of type int ( again of 2 byte ) .

If we create

float *pf;

it will create a pointer ( again of 2 bytes ) but pointing to a float ( of 4 byte ).

The difference makes sense when we try to read or move to the next block etc.

suppose we created a char type pointer to an int then while reading, it will just read the first byte leaving the second byte of int thus giving us wrong output.

Yes pointer size is always that of size of word on a particular architecture.

Actually pointer only contains starting address of a data type, there after how many bytes we have to read (e.g. 1 for char, 2 for int) depends upon type of pointer declared.

all pointers are the same size, they only differ on the platform and the amount memory you are trying to address. for example, on an 8051 platform it's 3 bytes, on an intel it's 32 or 64 bits wide.

Size of void pointer or size of character pointer are same because both variable contain address or we can say memory location

Use of pointer is to store a memory address.since any location in the memory have same type(characters or digits) of memory address, size is same for all pointer types.
