A pointer has its own memory address and size on the stack (4 bytes on x86), whereas a reference shares the same memory address (with the original variable) but also takes up some space on the stack. Since a reference has the same address as the original variable itself, it is safe t...
pointer variable has its own identity: a distinct, visible memory address that can be taken with the unary & operator and a certain amount of space that can be measured with the sizeof operator. it is possible to create a pointer to a pointer, but not a pointer to a reference or refere...
So the address involved is hided behind the scene and all you know is variable name x and internally is has association to location in the stack memory of the main function. Now have a look at the variable declaration below: int& refto_x = x; Here, refto_x is reference variable ...
So, this time the program compiled without any errors. Also, if you try to map the logic with output, you’ll find that an increment operation on reference variable ‘var’ affected the value of variable ‘a’. This proves that the reference variable and the original variable refer to the...
