Question

Given a vector of double like:


vector<double> dollars


Write code that will sum all of the values in the vector. Your code must work for no matter how many elements are in the vector. Also, print the total value just once like:


The total money in the bank is $xx.xx.
Where xx.xx is the actual total calculated. Do not worry about formatting to two decimal places, just output the answer. You may want to add some test values to the vector, but I am more concerned with the code Given a vector of double like:

Explanation / Answer

#include <iostream>
#include <vector>

using namespace std;

int main()
{
    vector<double> dollars; // declare vector
  
    bool more = true;
   while (more)    //enter double type values in it using push_bac
    {
       double d;
       cout << " Please enter dollars, 0 to quit: ";
       cin >> d;
       if (d == 0)
          more = false;
       else
          dollars.push_back(d);
    }
    double sum = 0;
    int i;
    for (i = 0; i < dollars.size(); i++) // sum of all elements of vector
       sum = sum + dollars[i];


       cout << " Sum = $"<<sum << " ";
  

    return 0;
}

Output:

Please enter dollars, 0 to quit: 100.34

Please enter dollars, 0 to quit: 200.56

Please enter dollars, 0 to quit: 300.67

Please enter dollars, 0 to quit: 400.85

Please enter dollars, 0 to quit: 500.56

Please enter dollars, 0 to quit: 0

Sum = $1502.98
