Aborted (core dumped)

"Aborted (core dumped)" is an error message that appears when a program crashes due to a segmentation fault or an illegal instruction. It means that the program attempted to access memory that it was not allowed to access, resulting in a crash. The "core dumped" part of the message indicates that the operating system has created a file containing a snapshot of the program's memory at the time of the crash, which can be used for debugging purposes.
