 After the increment() function is called, the value of the variable x will be incremented to 6.
-Here is an example of a complete program that passes a pointer to a function:
-
-```cpp
-#include <iostream>
-
-using namespace std;
-
-void increment(int *p) {
- *p += 1;
-}
-
-int main() {
- int x = 5;
- int *p = &x;

-## How to Return a Pointer from a Function in C++?
-
-To return a pointer from a function in C++, you need to declare the return type of the function as a pointer to the type of data that you want to return. For example, if you want to return a pointer to an integer, you would declare the return type of the function as int*.
-
-Here is an example of a function that returns a pointer to an integer:
-
-```cpp
-int* getIntPtr() {
- int* pInt = new int(10);
- return pInt;
-}
-```
-
-This function allocates a new integer on the heap and returns a pointer to it. The caller of the function is then responsible for deleting the integer when it is no longer needed.
-Here is an example of how to call the getIntPtr() function:
-
-```cpp
-int* pInt = getIntPtr();
-cout << *pInt << endl; // Prints "10"
-delete pInt;
-```
