11. (TCO 5) Using a loop, write a program that reads in exactly five integers and outputs the sum. (Points : 5)

int main()

{

int n1, n2, n3, n4, n5;

int sum = 0;

cout << "Enter five numbers: ";

cin >> n1;

cin >> n2;

cin >> n3;

cin >> n4;

cin >> n5;

sum = n1 + n2 + n3 + n4 + n5;

cout << "Sum = " << sum << endl;

return 0;
