已知2个按元素值递增有序顺序表La，Lb，设计一个算法将2个表的全部元素归并为一个按元素值递增有序的顺序表Lc。用C++写

#include<stdio.h>
#include<stdlib.h>

#define MAXSIZE 100

typedef struct {
    int elem[MAXSIZE];
    int length;
} SqList;

void InitList(SqList *L) {
    L->length = 0;
}

void InputList(SqList *L) {
    printf("请输入元素个数：");
    scanf("%d", &(L->length));
    printf("请输入元素：");
    for(int i=0; i<L->length; i++) {
        scanf("%d", &(L->elem[i]));
    }
}

void MergeList(SqList La, SqList Lb, SqList *Lc) {
    int i = 0, j = 0, k = 0;
    while(i < La.length && j < Lb.length) {
        if(La.elem[i] <= Lb.elem[j]) {
            Lc->elem[k++] = La.elem[i++];
        }
        else {
            Lc->elem[k++] = Lb.elem[j++];
        }
    }
    while(i < La.length) {
        Lc->elem[k++] = La.elem[i++];
    }
    while(j < Lb.length) {
        Lc->elem[k++] = Lb.elem[j++];
    }
    Lc->length = k;
}

void PrintList(SqList L) {
    for(int i=0; i<L.length; i++) {
        printf("%d ", L.elem[i]);
    }
    printf("\n");
}

int main() {
    SqList La, Lb, Lc;
    InitList(&La);
    InitList(&Lb);
    InputList(&La);
    InputList(&Lb);
    MergeList(La, Lb, &Lc);
    printf("归并后的顺序表Lc为：");
    PrintList(Lc);
    return 0;
}
