//Line 结构体的定义

//给Line赋值并打印
Line* distributeLine(Consumer* consumers,int num) {
    Line* lines = (Line*)malloc(sizeof(Line) * num);    //给线路分配内存
    int availableNum = num;    //剩余未被分配的客户数量
    Stop* firstStop = (Stop*)malloc(sizeof(Stop));

    int i = 0;

        lines[i]= findStops(consumers,num);    //将一组客户分配给第i条线路
        print(lines[i]);
        /*
        firstStop=lines[i].firstStop;
        int j = 0;
        firstStop->print();
        while (j < lines[i].size) {
            Stop* stop = firstStop->nextStop;
            stop->print();
            j++;
        }
        */
        //print(firstStop,lines[i].size);
        availableNum -= lines[i].size;        //未被分配的客户数量-第i条线路的客户数量
        i++;   
    }
    return lines;
}
//这是用于打印结构体Line的方法
void print(Line l){   
    Line line = l;
    int i = 0;
    Stop* stop = l.firstStop;
    print(*stop);
    while (i < l.size) {
        stop = stop->nextStop;
        print(*stop);
        i++;
    }
}

问题是当我单步刚进入到print方法时，形参就是我传入的参数，可是当我执行到下一步操作时，参数 l 却变成了一个莫名其妙的值，有大佬能帮我解决吗？感激不尽！！
