19.Write a program to find average marks of the subjects of a student. Throw multiple exceptions and define multiple catch statements to handle division by zero as well as array index out of bounds exceptions.

/* AVERAGE OF SUBJECTS USING MULTIPLE CATCH STATEMENTS*/

    int n,marks[10];

    float avg=0,tot=0;

    cout<<"\n enter the no of subjects";

    cin>>n;

    cout<<"\n enter the marks of a student\n"<<n<<"students\n";

    try

        {

            if(n>0&&n<=10)

            {

                for(int i=1;i<=n;i++)

                {

                    cout<<"enter marks of student"<<i<<":\t";

                    cin>>marks[i];

                    tot+=marks[i];

                }

            avg=tot/n;
