Question
Write a loop that sets each array element to the sum of itself and the next element, except for the last element which stays the same. Be careful not to index beyond the last element. Example:

Initial scores: 10, 20, 30, 40  
Scores after the loop: 30, 50, 70, 40  

The first element is 30 or 10 + 20, the second element is 50 or 20 + 30, and the third element is 70 or 30 + 40. The last element remains the same.

```c
#include <stdio.h>

int main(void) {
    const int SCORES_SIZE = 4;
    int bonusScores[SCORES_SIZE];
    int i;

    for (i = 0; i < SCORES_SIZE; ++i) {
        scanf("%d", &(bonusScores[i]));
    }

    /* Your solution goes here */

    for (i = 0; i < SCORES_SIZE; ++i) {
        printf("%d ", bonusScores[i]);
    }
    printf("\n");
}
```

### Explanation

This C program reads four integer values into an array called `bonusScores`. The purpose is to transform this array so that each element, except the last one, becomes the sum of itself and the next element. 

You are required to complete the solution by implementing the loop logic that calculates these sums while ensuring the last element remains unchanged. The modified array is then printed to demonstrate the results after the loop is applied.
