Assigning the address of a variable to the the pinter variable is nothing but the initialization of pointer.
eg. int x=10,*p = &x; or
int x=10, *p;
p = &x; Source: CoolInterview.com

p=&a;
The pointer must have same data type as that of variable whose address is stored into it. Source: CoolInterview.com
