Are these two equivalent?
int a=10;
int *p=a;
AND
int a=10;
int *p;
p=&a;
Does p hold address of a in both the cases!?

Are these two equivalent?
int a=10;
int *p=a;
AND
int a=10;
int *p;
p=&a;
Does p hold address of a in both the cases!?
In the first case
The value contained in the variable a is put into the variable p. So the value of the variable p is 10.
In the second case
The value in the variable a is 10 and the value in the variable p is the address of a.
In the first case even though the variable p is declared as a pointer to an int the value being put into the variable p is the value of the variable a, a value of 10. In the second case you are putting the address of the variable a into the variable p.
