用c++编写一个含sequence类的程序

非常感谢您的提问！以下是一个简单的含sequence类的C程序示例：

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

typedef struct {
int *data;
int length;
} Sequence;

void init(Sequence *seq, int length) {
seq->data = (int *)malloc(length * sizeof(int));
seq->length = length;
}

void set(Sequence *seq, int index, int value) {
seq->data[index] = value;
}

int get(Sequence *seq, int index) {
return seq->data[index];
}

void print(Sequence *seq) {
for (int i = 0; i < seq->length; i++) {
printf("%d ", seq->data[i]);
}
printf("\n");
}

int main() {
Sequence seq;
init(&seq, 5);
set(&seq, 0, 1);
set(&seq, 1, 2);
set(&seq, 2, 3);
set(&seq, 3, 4);
set(&seq, 4, 5);
print(&seq);
return 0;
}

希望这个程序能够帮助您！
