学习c++动态分配数组的顺序表基本操作（王道数据结构顺序表）c和c++在混用 malloc free是c的 &传值引用时c++的

#define InitSize 10
typedef struct{
    ElemType *data;//指针
    int MaxSize;
    int length;
}SeqList;
//初始化
void InitList(SeqList &L)
{
    L.data = (ElemType *)malloc(InitSize*sizeof(ElemType));
    L.length = 0;
    L.MaxSize = InitSize;
}
void IncreaseSize(SeqList &L,int len)
{
    int *p = L.data;
    L.data = (ElemType *)malloc((MaxSize+len)*sizeof(ElemType));
    for(int i = 0;i
