Rewrite the entire following code segment using a switch statement instead of the if/else if.                                                                                                                                  int n, a = 1, b = 2, c = 3, d = 4;                                   cin >> n; if (n = = 3)     a = a + 1; else if (n = = 7 || n = = 8)                                                            b = b + 1; else if (n > 10 && n < 13)     c = c + 1;                                                                 else                                                                                                                                 d = d + 1; cout << a << "  " <<  b << "  " << c << "  " << d << endl;

change while to do #include <iostream>using namespace std;int main(){int n1,high=-1,low=101,tot=0;double avg=0; while (true)// condition always true{// body of loopcout <<"enter a grade,-1 to stop"<<endl;cin >> n1;if (n1==-1)break;++tot;avg+=n1;if (high < n1)high=n1;if (low >n1)low=n1; } //end loop cout<<"Total number of grades is "<<tot<<endl; // prints total number of grades that were inputcout<<"The highest grade is "<<high<<endl; // prints the highest gradecout<<"The lowest grade is "<<low<<endl; // prints the lowest gradeif (tot > 0)cout<<"The average grade is "<<avg/tot<<endl; //calculates the average grade return 0;}
