## C-programming basic algorithm: Exercise-63 with Solution

Write a C program to check a given array of integers and return true if the given array contains either 2 even or 2 odd values all next to each other.

C Code:

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

int main(void){
int arr_size;
int array1[] = {1, 2, 3, 4 };
arr_size = sizeof(array1)/sizeof(array1);
printf("%d",test(array1, arr_size));
int array2[] = {3, 3, 5, 5, 5, 5};
arr_size = sizeof(array2)/sizeof(array2);
printf("\n%d",test(array2, arr_size));
int array3[] = {2, 5, 5, 7, 8, 10};
arr_size = sizeof(array3)/sizeof(array3);
printf("\n%d",test(array3, arr_size));
}

int test(int numbers[], int arr_size)
{
int tot_odd = 0, tot_even = 0;

for (int i = 0; i < arr_size; i++)
{
if (tot_odd < 2 && tot_even < 2)
{
if (numbers[i] % 2 == 0)
{
tot_even++;
tot_odd = 0;
}
else
{
tot_odd++;
tot_even = 0;
}
}
}
}
``````

Sample Output:

```0
1
1
```
