Answer:
C++ Program
#include<iostream>
using namespace std;
int main()
{
int n,bt[20],wt[20],tat[20],avwt=0,avtat=0,i,j;
cout<<"Enter total number of processes(maximum 20):";
cin>>n;
cout<<"\nEnter Process Burst Time\n";
for(i=0;i<n;i++)
{
cout<<"P["<<i+1<<"]:";
cin>>bt[i];
}
wt[0]=0; //waiting time for first process is 0
//calculating waiting time
for(i=1;i<n;i++)
{
wt[i]=0;
for(j=0;j<i;j++)
wt[i]+=bt[j];
}
cout<<"\nProcess\t\tBurst Time\tWaiting Time\tTurnaround Time";
//calculating turnaround time
for(i=0;i<n;i++)
{
tat[i]=bt[i]+wt[i];
avwt+=wt[i];
avtat+=tat[i];
cout<<"\nP["<<i+1<<"]"<<"\t\t"<<bt[i]<<"\t\t"<<wt[i]<<"\t\t"<<tat[i];
}
avwt/=i;
avtat/=i;
cout<<"\n\nAverage Waiting Time:"<<avwt;
cout<<"\nAverage Turnaround Time:"<<avtat;
return 0;
