Some of the errors that you may encounter are • Dereference of invalid or uninitialized pointer • Insufficient or unallocated memory for the operation • Reuse of storage after freeing it • Double freeing of memory • Incorrect use of pointer arithmetic • Returning a pointer that is no longer valid • Trying to free variables in the stack • assigning incompatible types • Array index out of bounds • Program logic confuses pointer and reference types Part II – In this part, you are asked to write a program in Perl or Shell. The program Should process folders, sub-folders, files, and patterns in files. You need to understand how to pass and process command line arguments in Perl or Shell, how to use simple Regular Expressions such as direct pattern matching’s, patterns starting with something, patterns ending with something, refereeing back to a pattern that was matched etc etc. We will discuss more of this in the next lesson. Part III – This is a good old C program that you need to write. You must understand, C functions, malloc and free, C arrays, resizing, function pointers, void*, generic data types, functions with variable number of arguments, bit operations, etc. Basically, any skill that you learned in labs is extremely useful.
