C++ Exercises: Check whether a given array of integers contains 5's and 7's

C++ Basic Algorithm: Exercise-103 with Solution

Write a C++ program to check whether a given array of integers contains 5's and 7's.

Sample Solution:

C++ Code :

#include <iostream>

using namespace std;

static bool test(int nums[], int arr_length)
         {
             for (int i = 0; i < arr_length; i++)
            {
                if (nums[i] == 5 || nums[i] == 7) return true;
            }

            return false;
          }  
               
int main() 
 {  
  int nums1[] = { 1, 5, 6, 9, 10, 17 };
  int arr_length = sizeof(nums1) / sizeof(nums1[0]);
  cout << test(nums1, arr_length) << endl; 
  int nums2[] = { 1, 4, 7, 9, 10, 17 };
  arr_length = sizeof(nums2) / sizeof(nums2[0]);
  cout << test(nums2, arr_length) << endl;
  int nums3[] = { 1, 1, 2, 9, 10, 17 };
  arr_length = sizeof(nums3) / sizeof(nums3[0]);
  cout << test(nums3, arr_length) << endl;
  return 0;    
}

Sample Output:

1
1
0
