Whenever you are declearing a pointer variable, you need to also mention to which type of variable the pointer points to. 

We can use this kind of syntax. 

int * p1;      --> p1 is pointing to a variable of type int
void *p2;     --> p2 can point to any data type. You need to cast this to any other data type pointer before using it. This gives flexibility to use same pointer for all data types. 
float *p3;    --> p3 is pointing to a variable of type float
double *p4; --> p4 is pointing to a variable of type double
