How do I assign a pointer to a variable?

Question

Suppose we have a variable k which is equal 7:

int k=7;
int t=&k;

But this does not work. What's the mistake?

Answer 1

You probably meant:

int k=7;
int *t=&k;

Answer 2

&k takes the address of k . You probably mean

int *t = &k;

I have a good read for you: Alf P. Steinbach's pointer tutorial .

Answer 3

You declare t as of type int and try to assign a value of type int* . int* cannot implicitely cast to type int which leads to the error you are observing. The solution is simple: declar t as int* . However, it seems you have no deeper understanding of pointers so you should fix that first before trying anything else.
