Process finished with exit code 143 (interrupted by signal 15: SIGTERM) error message
Hi! I wrote a program using dynamic arrays and got the error message "Process finished with exit code 143 (interrupted by signal 15: SIGTERM)".
Can someone help me understand how to change my code, so that error message does not come up?

As formatted with a couple of minor changes (void return from printArray):
Could be due to printArray() specifying a return type - but not returning a value.

Several issues
- readInput wasn't using logicalSize to track usage
- readInput was ignoring the return result of expandArr
- expandArr was deleting the memory it had just allocated.
- searchNum used a bogus size of zero as well.
Now valgrind doesn't detect overruns, or leaks.
