SINGLE USER CONTIGOUS SCHEME:

INPUT THE SIZE OF MEMORY
DISPLAY THE SIZE OF THE OS BY COMPUTING 20% OF THE MEMORY
INPUT THE NUMBER OF JOBS
EXAMPLE: IF THE NUMBER OF JOB IS ENTERED THE SCREEN WILL GIVE YOU AN OUTPUT LIKE THIS
JOB 1;
JOB 2;
JOB 3;
JOB 4;

SET THE FOLLOWING VALUE OF THE MEMORY REQUIREMENT OF EACH JOBS: 15,30,40,2
ASSUMING THE MEMORY SIZE IS 64MB
DISPLAY THE WASTED MEMORY FOR EACH JOBS AND THE AVERAGE WASTED MEMORY FOR ALL THE JOBS
DISPLAY THE PERCENTAGE OF ALL THE JOBS:

64-15=49 15 MEMORY USAGE
64-30=30 30 MEMORY USAGE
64-40=24 40 MEMORY USAGE
64-2=62 2 MEMORY USAGE

I didnt how to do it please helpme

Nobody eve told you that posting in CAPITAL letters is considered shouting and in your case kind of impolite ?
And where did you pickup the rule that OS takes 20% of memory ?

@lockwater now we know you can type. Can you show us that you can think? just asking as we have this nice rule We only give homework help to those who show effort
