C++ Exercises: Compute the sum of the numbers in a given array except those numbers starting with 5 followed by atleast one 6

C++ Basic Algorithm: Exercise-101 with Solution

Write a C++ program to compute the sum of the numbers in a given array except those numbers starting with 5 followed by atleast one 6. Return 0 if the given array has no integer.

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;
static int test(int nums[], int arr_length)
     {
      int sum = 0;
      int inSection = 0;
      int flag = 0;
      for (int i = 0; i < arr_length; i++)
            {
                inSection = 0;
                if (nums[i] == 5)
                {
                inSection = 0;
                flag = 1;
                }
                if (inSection == 0 && nums[i] == 6)
                {
                  if (flag == 1)
                  {
                  sum = sum - 5;
                  inSection = 1;
                  }
                   flag = 0;
                }
                if (inSection == 0)
                {
                  sum += nums[i];
                }
            }
            return sum;
           }
int main()
 {
  int nums1[] = { 1, 5, 9, 10, 17 };
  int arr_length = sizeof(nums1) / sizeof(nums1[0]);
  cout << "Sum of the numbers of the said array except those numbers starting with 5 followed by atleast one 6: " << endl;
  cout << test(nums1, arr_length) << endl;
  int nums2[] = { 1, 5, 6, 9, 10, 17 };
  arr_length = sizeof(nums2) / sizeof(nums2[0]);
  cout << "Sum of the numbers of the said array except those numbers starting with 5 followed by atleast one 6: " << endl;
  cout << test(nums2, arr_length) << endl;
  return 0;
}

Sample Output:

Sum of the numbers of the said array except those numbers starting with 5 followed by atleast one 6: 
42
Sum of the numbers of the said array except those numbers starting with 5 followed by atleast one 6: 
37

Previous: Write a C++ program to compute the sum of values in a given array of integers except the number 17. Return 0 if the given array has no integer.
Next: Write a C++ program to check if a given array of integers contains 5 next to a 5 somewhere.
