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;}
