Your are asked to calculate the individual and the average waiting time of the project.

Also find their individual and the average turnaround time of each project.

INPUT :
Line 1 : No of Process

Line 2 : Burst time of each process

TEST CASE 1

OUTPUT

Pid BT WT TAT
P[1] 5 0 5
P[2] 4 5 9

Average Waiting Time:7
Average Turnaround Time:13

Code :

#include <iostream>

    cout<<"Pid BT WT TAT\n";
   for(int i=0;i<size;i++)
    {
       cin>>burst[i];
        
    }
  for(int i=0;i<size;i++)
  {
    cout<<"P["<<i+1<<"] "<<burst[i]<<" "<<ini<<" "<<burst[i]+ini<<"\n";
    ini=burst[i]+ini;
  }
   for(int i=1;i<=size;i++)
    {
     turna[i]=turna[i-1]+burst[i-1];
       ta+=turna[i];
    }

   for(int i=1;i<size;i++)
    {
     wait[i]=wait[i-1]+burst[i-1];
       avg+=wait[i];
    }
   cout<<"Average Waiting Time:"<<avg/size;
   cout<<"\nAverage Turnaround Time:"<<ta/size;
 return 0;
