C++ Error Notes
Segmentation Fault (Segmentation violation) error
Issue
Accessing memory that is not allocated or accessing memory outside the bounds of an allocated block.
Details
This error often occurs when dereferencing a null pointer or accessing an array index beyond its bounds. For example:
int* ptr = nullptr;
*ptr = 10; // Dereferencing a null pointer
int arr[5];
arr[5] = 10; // Accessing memory outside the bounds of the array
Solution
To avoid segmentation faults, ensure pointers are properly initialized before use and verify array indices are within bounds before accessing elements.
