        exit(0);

    for(i=0;i<n;i++)
        scanf("%d",pscore[i]);
    max=pscore[0];
    min=pscore[0];

    for(i=0;i<n;i++)
        if(pscore[i]>max)
        max=pscore[i];

        min=pscore[i];
        aver+=pscore[i];

    printf("max=%lf min=%lf aver=%lf",max.min,aver/n);

}

求解哪里错了  
报错是F:\2\main.cpp|28|error: request for member 'min' in 'max', which is of non-class type 'int'|

scanf("%d",pscore[i]);
改
scanf("%d",&pscore[i]);

你要是用下标使用指针的话，那如果scanf你就要加上取址符。还有个小建议就是，头文件如果包含了stdlib那就不用包含malloc了，分配内存的函数stdlib都有。这个是代码更加简洁的建议而已
