Question 15 int x = 0; for (x = 10; x< 1 ; x = x + 2) cout << "Hello World"; how many times does this for-loop execute cout << "Hello World"; 3 N

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;}

. How many times does the code snippet given below display "Loop Execution"?   for (i = 0; i != 9; i++) {    cout << "Loop Execution" << endl; }

What will the following code display? int x = 0; while (x < 5) { cout << x << " "; x++; } OA) 0 1 2 3 4 O B) º 1 2 3 4 OC) 0 1 2 3 4 5 OD) This is an infinite loop
