I am trying to create a program that calculates the sum of 1 through 100 using an array in C++. Can you explain what I'm doing incorrectly?

#include

using namespace std;

int main() { const int NUMBERS = 100; int values[NUMBERS]; int sum = 0; for (int i = 1; i <= NUMBERS; i++) { values[i] = sum; sum = sum + values[i]; cout << "Sum equals " << i << values[i] << endl; //cout << "Salary[" << loopIndex << "]: " << salaries[loopIndex] << endl; }

return 0; }
