A pointer in C++ is used to share a memory address among different contexts (primarily functions). They are used whenever a function needs to modify the content of a variable, but it does not have ownership.
In order to access the memory address of a variable, , prepend it with sign. For example, &val returns the memory address of .
This memory address is assigned to a pointer and can be shared among functions. For example, assigns the memory address of to pointer . To access the content of the memory pointed to, prepend the variable name with a *. For example, *p will return the value stored in and any modification to it will be performed on .
The function is declared with a
void return type, so there is no value to return. Modify the values in memory so that contains their sum and contains their absoluted difference. Sample Input 0
