C++ Exercises: Check two given arrays of integers of length 1 or more and return true if they have the same first element or they have the same last element

C++ Basic Algorithm: Exercise-83 with Solution

Write a C++ program to check two given arrays of integers of length 1 or more and return true if they have the same first element or they have the same last element.

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;

bool test(int a1[], int arr_length1, int a2[], int arr_length2)
          {
           return a1[0] == a2[0] || a1[arr_length1 - 1] == a2[arr_length2 - 1];
          } 
          
int main() 
 {  
  int arr_length1, arr_length2;	
  int nums11[] = {10, 20, 40, 50};	
  int nums12[] = {10, 20, 40, 50};	
  arr_length1 = sizeof(nums11) / sizeof(nums11[0]);
  arr_length2 = sizeof(nums12) / sizeof(nums12[0]);
  cout << test(nums11, arr_length1, nums12, arr_length2) << endl; 
  int nums21[] = {10, 20, 40, 50};	
  int nums22[] = {10, 20, 40, 5};	
  arr_length1 = sizeof(nums21) / sizeof(nums21[0]);
  arr_length2 = sizeof(nums22) / sizeof(nums22[0]);
  cout << test(nums11, arr_length1, nums12, arr_length2) << endl; 
  int nums31[] = {10, 20, 40, 50};	
  int nums32[] = {1, 20, 40, 5};	
  arr_length1 = sizeof(nums31) / sizeof(nums21[0]);
  arr_length2 = sizeof(nums32) / sizeof(nums22[0]);
  cout << test(nums31, arr_length1, nums32, arr_length2) << endl;
  return 0;    
}

Sample Output:

1
1
0
