C/C++ :: Read Numbers From Cin Then Sum Up And Stopping When 0 Entered

Write a program that reads numbers from cin and then sums them, stopping when 0 has been entered. Add the following to your program:

-A counter within the while loop that keeps track of the number of inputs entered.
-A comment that determines if the total value is less than 100 or greater than 100, as in the sample output
-Switch statements to determine the total number of inputs

Sample output:

Enter numbers, one per line. Enter 0 to end:
7
8
6
5
5
9
8
0

The total was 48.
The total number of inputs read is 8.
The total is less than 100.

The code that I've got so far lets me keep track of the inputs entered, and displays the total of the values, but I'm not sure how to do the part where it determines if the value is greater or less than 100.

#include <iostream>
using namespace std;
int main() {
int val, total=0;
int i=0;
cout << "Enter numbers, one per line. Enter 0 to end:
";
