去掉有序数组中的重复元素 c/c++

去掉有序数组中的重复元素:

int RemoveDuplates(int A[], int nCnt)
{
    int nNewLen = ;
    int j       = ;

    for (int i = , j = ; i < nCnt && j < nCnt; i++)
    {
        while(j < nCnt && A[i] == A[j])
            j++;

        if( j > i +  && j < nCnt)
            A[i + ] = A[j];

        nNewLen++;
    }

    return nNewLen;
}
