sum_arrays.cpp

//Write a function that takes an array of numbers and returns the sum of the numbers. The numbers can be negative or non-integer. If the array does not contain any numbers then you should return 0.
//Examples

//Input: [1, 5.2, 4, 0, -1]
//Output: 9.2

//Input: []
//Output: 0

//Input: [-2.398]
//Output: -2.398

#include <vector>

int sum(std::vector<int> nums) {
  int sum = 0;
  
  for (int i = 0; i < nums.size(); i++) {
    sum += nums[i];
  }
  
  return sum;
