Answer 2

Pointer is a variable which hold the address of another variable.

The general syntax of declaring pointer variables can be given as below:

data_type *ptr_name;

Here, data_type is the data type of the value that the pointer will point to.

For example,

int *pnum;

char *pch;

float *pfnum;

In each of the aforegiven statements, a pointer variable is declared to point to a variable of the specified data type. Although all these pointers, pnum, pch and pfnum point to different data types, the will occupy same amount of space in memory.
