Answer:
Replace /* Your solution goes here */
with
for (i = 0; i < SCORES_SIZE-1; ++i) {
bonusScores[i] += bonusScores[i+1];
}
Explanation:
In C++, the index of an array starts from 0 and ends at 1 less than the size of the array;
Using the analysis in the question, the above code (in the answer section) iterates from the index element (element at 0) to the second to the last element (element at size - 2)';
This is to ensure that the element of the array only adds itself and the next element;except for the last index which remains unchanged
The following operation is done in each iteration.
When i = 0,
<em>bonusScores[0] = bonusScores[0] + bonusScores[0+1];
</em>
<em>bonusScores[0] = bonusScores[0] + bonusScores[1];
</em>
<em>bonusScores[0] = 10 + 20</em>
<em>bonusScores[0] = 30</em>
When i = 1,
<em>bonusScores[1] = bonusScores[1] + bonusScores[1+1];
</em>
<em>bonusScores[1] = bonusScores[1] + bonusScores[2];
</em>
<em>bonusScores[1] = 20 + 30</em>
<em>bonusScores[1] = 50</em>
<em />
When i = 2,
<em>bonusScores[2] = bonusScores[2] + bonusScores[2+1];
</em>
<em>bonusScores[2] = bonusScores[2] + bonusScores[3];
</em>
<em>bonusScores[2] = 30 + 40</em>
<em>bonusScores[2] = 70</em>
<em />
<em>This is where the iteration stops</em>
