IOT instruction (core dumped)

"IOT" stands for "Illegal Instruction". When a program encounters an illegal instruction, the operating system terminates the program and produces a "core dump". This dump is a file that contains a snapshot of the program's memory at the time of the crash. It can be useful in troubleshooting the issue that caused the crash.

There are several possible causes for an IOT error, including:

1. The program is trying to execute an instruction that is not supported by the CPU.
2. The program is trying to execute an instruction that is not allowed by the operating system.
3. The program has become corrupted or damaged.

To resolve an IOT error, you can try the following:

1. Make sure the program is compatible with your CPU and operating system.
2. Update the program to the latest version.
3. Repair or reinstall the program.
4. Check for any system updates or patches that may address the issue.
5. If the issue persists, contact the program's support team for further assistance.
