Question: how can i Write a simple C program that creates a pointer to an integer, sets it to NULL, and then tries to dereference it.

  1. how can i Write a simple C program that creates a pointer to an integer, sets it to NULL, and then tries to dereference it. Compile this into an executable using gcc (see the example earlier).Run the program directly, using the debugger, and under valgrind. What is the error? How do the error messages differ from tool to tool?
  2. Write a program that allocates memory using malloc but forgets to free it before exiting. What happens when this program runs? Can you use gdb to find any problems with it? How about valgrind (this time with the --leak-check=yes flag)?
