Answer:
d) By dereferencing intpoint with *.
Explanation:
When we want to change the value pointed by an pointer.We use dereferencing operator(*).For example:-
int b=89;
int *a=&b;
In these statements the integer a points to the value stored in integer b.
If we directly print a the address of variable b will be printed on the screen.So to print the value we have to derefer it.This can be done as following:-
cout<<*a<<endl;
Output = 89.
We are using dereferencing operator (*) in it.
