﻿ C : Check two arrays have the same first and last element

# 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-programming basic algorithm: Exercise-35 with Solution

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

C Code:

``````#include <stdio.h>
#include <stdlib.h>

// Function prototype for 'test'
int test(int nums1[], int nums2[], int arr_size1, int arr_size2);

int main(void){
// Test case 1
int array11[] = {10, 20, 40, 50};
int arr_size11 = sizeof(array11)/sizeof(array11);
int array12[] = {10, 20, 40, 50};
int arr_size12 = sizeof(array12)/sizeof(array12);
printf("%d",test(array11,array12,arr_size11,arr_size12));

// Test case 2
int array21[] = {10, 20, 40, 50};
int arr_size21 = sizeof(array21)/sizeof(array21);
int array22[] = {11, 20, 40, 51};
int arr_size22 = sizeof(array22)/sizeof(array22);
printf("\n%d",test(array21,array22,arr_size21,arr_size22));
}

// Definition of the 'test' function
int test(int nums1[], int nums2[], int arr_size1, int arr_size2)
{
// Checking if the first element of the first array is equal to the first element of the second array
// or if the last element of the first array is equal to the last element of the second array
return nums1 == nums2 || nums1[arr_size1 - 1] == nums2[arr_size2 - 1];
}
``````

Sample Output:

```1
0
```
