**Code and Diagram Description Exercise**

Given the following code, describe the diagram that would represent the situation with the variables:

```c
int A = 10;
int B = 42;
int* p;
int* q;
int* x;
p = &A;
q = &B;
x = p;
p = q;
```

**Options for diagram description:**

- ( ) Two boxes - one with 10, one with 42 - and three arrows which all point to 42
- ( ) Two boxes - one with 10, one with 42 - and two arrows pointing to 10 and one pointing to 42
- ( ) Two boxes - one with 10, one with 42 - and one arrow pointing to 10 and two pointing to 42
- ( ) Two boxes - one with 10, one with 42 - and three arrows which all point to 10

**Explanation:**

This exercise involves understanding pointer variables and their assignments in relation to the memory addresses of integer variables `A` and `B`. Students are asked to choose the correct diagram representation based on the final state of the pointers.
