用c语言写顺序表.已知A、B分别是m、n位（位数为10-30的随机正整数）的随机正整数，编写程序给出这两个正整数相加的结果。如：A=47858628539074，B= 212821064467，C=A+B=48071449603541

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

#define MAX_LEN 30

typedef struct {
int *data;
int len;
} SeqList;

void initList(SeqList *L, int len) {
L->data = (int *)malloc(len * sizeof(int));
L->len = len;
srand(time(NULL));
for (int i = 0; i < len; i++) {
L->data[i] = rand() % 10;
}
}

void printList(SeqList L) {
for (int i = 0; i < L.len; i++) {
printf("%d", L.data[i]);
}
printf("\n");
}

void add(SeqList A, SeqList B, SeqList *C) {
int carry = 0;
int i = A.len - 1;
int j = B.len - 1;
int k = C->len - 1;

int sum = carry;
if (i >= 0) {
sum += A.data[i];
i--;
}
if (j >= 0) {
sum += B.data[j];
j--;
}
C->data[k] = sum % 10;
carry = sum / 10;
k--;
}
if (carry > 0) {
C->data[k] = carry;
}
}

int main() {
