Problems with dynamic array

At the same time, they may be inferior in the speed of adding data. In the case of lists, it is enough to change internal links, while in dynamic arrays, it is necessary to move data in memory. The efficiency of working with dynamic arrays is increased by buffer windows, so-called gap buffers, and multi-level vectors — tiered vectors.
Writing to another memory area
Reason: Memory allocation failure when using an array.
Conclusion: you need to check the pointer for NULL. If after memory russia rcs data allocation the pointer value is zero, using such an array will cause the system to hang.

Problems with dynamic array
Re-deleting the pointer
Reason: Attempted to delete an array that had already been deleted.
Conclusion: After deleting an array, you should reset the pointer to zero to quickly detect errors.
Array out of bounds
Reason: Writing an element with a negative index or an index that is outside the array bounds.
Memory leak
Cause: Unused memory not being released. If this happens in a function that is called many times, resources are quickly exhausted.
