c++ - Do the addresses of variables, declared just after each other, precede each other? -

i learning c++ pointers , have following question.

when declare example 3 variables this:

int = 0, b = 1, c = 2; 

will there variable have addresses precede each other... when address of a ends, address of b start immediately?

additionally, please provide me links of tutorials or books can learn how computer works memory (bit, byte...), because not quite understand how computer, variables , data work , can't useful link anywhere.

thanks in advance :)

it depends upon compiler how assign address's variable.

in case address's might sequential or might not be.

you can verify code :

#include"iostream"  using namespace std;  int main() {     int = 0, b = 1, c = 2;      cout<<"address of : "<<&a<<endl<<"address of b : "<<&b<<endl<<"address of c : "<<&c<<endl;      return 0; } 

so if need play around address of variable, take pointer of type , use pointer access or change variable.

example :

int *p_a = &a; int *p_b = &b; int *p_c = &c;
