Basic memory management (use to be:help!)

Hi i did do some basic c programming about seven years ago and have now just returned to college. I would really appreciate it if anyone could help with this, am sure its qiute straight forward but.......
Write C program that implements some basic memory management
and scheduling algorithm facilities
From the main menu the user should be allowed to:

input a process table

run memory management

run scheduling algorithms

exit program

PID A B P S
101 0 5 3 6
102 0 4 2 4
103 2 3 1 3
104 3 2 2 4
105 3 3 3 3

Have no idea what this means, am pulling my hair out ............if i had any left!!!

In the future please use an appropriate subject title. You can refer to the sticky thread at the top of this forum for more information on how to post a question.
