10. (30 points) This exercise asks you to look at a standard UNIX C library for problems with robustness. Please write three programs that use functions from the standard I/O library. You are to call the functions in such a way that they cause the program to crash, or generate unpredictable results. To demonstrate "crashing," use gdb output to show that the crash occured within the standard I/O library function. To demonstrate "unpredictable results," run your program (without changes) on at least two different types of computers in the CSIF (for example, once on a DEC and once on an SGI) and show that the results of the function differ (you can use gdb, or print the relevant values). Important note:you must supply the correct type of argument for the functions. You may not, for example, pass a character pointer where a file pointer is expected.
    Please submit both the programs and typescripts for each program showing the crash or the unpredictable results.
