cout中的执行顺序_a++和++a

int main()
{
/*
    char* str = NULL;
    setmemory(&str, 100);
    strcpy(str, "hello");
    cout << str << endl;
*/
    int arr[] = {6,7,8,9,10};
//    int* ptr = arr;
    int* mp = arr;
//    *(++ptr) += 123;     //arr[1] = 130
    cout << *mp << " " << *(mp++) << " " << *mp << endl;　　　//6 6 7
　　cout << *mp << " " << *(++mp) << " " << *mp << endl;      //6 7 7 
    cout << *mp << endl;
//    printf("%d,%d,%d", *ptr,*(ptr++),*ptr);
    //    cout << *ptr << endl << *(++ptr) << endl;
    return 0;
