C++ Exercises: Check a given array of integers of length 1 or more and return true if the first element and the last element are equal in the given array

C++ Basic Algorithm: Exercise-82 with Solution

Write a C++ program to check a given array of integers of length 1 or more and return true if the first element and the last element are equal in the given array.

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;

bool test(int nums[], int arr_length)
          {
           return arr_length > 0 && nums[0] == nums[arr_length - 1];
          } 
          
int main() 
 {  
  int arr_length;	
  int nums1[] = {10, 20, 40, 50 };	
  arr_length = sizeof(nums1) / sizeof(nums1[0]);
  cout << test(nums1, arr_length) << endl; 
  int nums2[] = {10, 20, 40, 10};	
  arr_length = sizeof(nums2) / sizeof(nums2[0]);
  cout << test(nums2, arr_length) << endl;
  int nums4[] = {12, 24, 35, 55};	
  arr_length = sizeof(nums4) / sizeof(nums4[0]);
  cout << test(nums4, arr_length) << endl;

  return 0;    
}

Sample Output:

0
1
0

Previous: Write a C++ program to check a given array of integers of length 1 or more and return true if 10 appears as either first or last element in the given array.
Next: 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.
