Question

I am getting an unusual result when attempting to place a value in an array. I have an array table[] of a simple class result{ int score, long time, string ID} Intention is to have a sort of leader board. My code happily finds the correct place to insert a new score if it is in the top 10.

    int ix = 0; 
    int jx = 10; //
    while ( ix < jx )
    {
        if (points > sTable[ix].points)
        {
            // score is higher move records down
            for (jx = mNumRecords - 1; jx >ix ; jx--)
            {
                sTable[jx] = sTable[jx -1];
            }
            //now add new score
            sTable[ix].score = score; // all good until here
            sTable[ix].time = time;


        }

        ix++;           
    }

问题在于,当我试图用可衡量的[六]分点插入计分;

该数值为可兑换[ix]分,也为可兑换[ix +1]分。

重复的是,它以六分之一的价值发生,我通过该守则单行,只要我只能够告诉指挥员一次。

是否有人看到这一点?

Answer 1

这是因为你抄录了标语中提及阵列的下一个要素。您应复制价值,或提出新目标:

Option A:

// score is higher move records down
for (jx = mNumRecords - 1; jx >ix ; jx--)
{
    sTable[jx].time = sTable[jx -1].time;
    sTable[jx].score = sTable[jx -1].score;
}
//now add new score
sTable[ix].score = score; // all good until here
sTable[ix].time = time;

备选案文B:

for (jx = mNumRecords - 1; jx >ix ; jx--)
{
    sTable[jx] = sTable[jx -1];
}
sTable[ix] = new Result(score, time, ""); // Or however you construct the object
