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;

}
