### Code Analysis: Identifying Potential Errors or Crashes**Problem Statement:**Examine the following code segment to determine which line could cause an error or a program crash, and explain why.```cppLine 1: int *p1, *p2;Line 2: p1 = new int;Line 3: p2 = new int;Line 4: *p1 = 11;Line 5: *p2 = 0;Line 6: p2 = p1;Line 7: cout << *p1 << " " << *p2 << endl;Line 8: delete p1;Line 9: delete p2;```**Explanation:**- **Line 1:** Two integer pointers, `p1` and `p2`, are declared.- **Lines 2-3:** Memory is dynamically allocated for two integers, and `p1` and `p2` point to these memory locations.- **Lines 4-5:** The allocated memory is assigned values 11 and 0, respectively.- **Line 6:** `p2` is assigned the address stored in `p1`. Now both `p1` and `p2` point to the same memory location. The int value originally pointed to by `p2` is now a memory leak because its address is no longer stored.- **Line 7:** The values pointed to by `p1` and `p2` are output. They will print the same value because they point to the same location.- **Line 8:** Memory at the location pointed to by `p1` is deallocated.- **Line 9:** Attempts to deallocate memory at the location pointed to by `p2`. Since `p2` points to the same location as `p1`, this leads to a double deletion error, causing undefined behavior or a crash.**Conclusion:**The potential error occurs at **Line 9** due to the double deletion of the memory pointed to by both `p1` and `p2`. This results in undefined behavior. Proper care must be taken to ensure that each memory location is deleted only once.

Answer: Given code is: Line1: int *p1,*p2;Line2: p1 = new int;Line3: p2 = new int;Line4: *p1 =…
