Size of variable

Question

Int var=5532;
Int*varsize=var;
Cout<< //i want to print pointers size in bytes?

Answer 1

int var = 5532;
int *varsize = &var;
std::cout << sizeof(varsize);

Regardless of the data type they are pointing to, pointers have fixed size and is related to the architecture. On 32-bit machine the size of a pointer is 32bits (4 bytes), while on 64 bit machine it is 8 bytes.

Answer 2

And what if i want to print size of var

Answer 3

int var = 5532;
int *varPtr = &var;
cout<<sizeof(var)<<endl; //without using a pointer
cout<<sizeof(*varPtr)<<endl; //using a pointer
