Answer / Avi Mantala
A pointer is a variable that stores the memory address of another variable. In C, you can declare a pointer by placing an asterisk (*) before the variable name.nnFor example:nn```cnint num = 42;nint *ptr = #nprintf("The value of num is: %d
", num);nprintf("The address of num is: %p
", &num);nprintf("The value stored in the pointer ptr is: %p
", ptr);nprintf("The value that the pointer ptr points to is: %d
", *ptr);n```
