Run a program that calls fork(). Before calling fork(), have the main process access a variable (e.g., x) and set its value to some-thing (e.g., 100). What value is the variable in the child process? What happens to the variable when both the child and parent change the value of x?

Please help me to do the following tasks;

1. Write out the code to your program.
2. Run the program and show your result.
3. What value is the variable in the child process?
4. What happens to the variable when both the child and parent change the value of x?
