建立三元组抽象数据类型定义的头文件，编程实现三元组的基本操作，输出任意三元组的最大值和最小值。

以下是三元组抽象数据类型定义的头文件：

#ifndef TRIPLE_H
#define TRIPLE_H

typedef struct {
    int first;
    int second;
    int third;
} Triple;

Triple createTriple(int first, int second, int third);
int getFirst(Triple t);
int getSecond(Triple t);
int getThird(Triple t);
void setFirst(Triple *t, int first);
void setSecond(Triple *t, int second);
void setThird(Triple *t, int third);
int getMax(Triple t);
int getMin(Triple t);

#endif

以下是三元组的基本操作的实现：

#include "triple.h"

Triple createTriple(int first, int second, int third) {
    Triple t;
    t.first = first;
    t.second = second;
    t.third = third;
    return t;
}

int getFirst(Triple t) {
    return t.first;
}

int getSecond(Triple t) {
    return t.second;
}

int getThird(Triple t) {
    return t.third;
}

void setFirst(Triple *t, int first) {
    t->first = first;
}

void setSecond(Triple *t, int second) {
    t->second = second;
}

void setThird(Triple *t, int third) {
    t->third = third;
}

int getMax(Triple t) {
    int max = t.first;
    if (t.second > max) {
        max = t.second;
    }
    if (t.third > max) {
        max = t.third;
    }
    return max;
}

int getMin(Triple t) {
    int min = t.first;
    if (t.second < min) {
        min = t.second;
    }
    if (t.third < min) {
        min = t.third;
    }
    return min;
}

以下是输出任意三元组的最大值和最小值的示例代码：

#include <stdio.h>
#include "triple.h"

int main() {
    Triple t = createTriple(3, 7, 2);
    printf("Max: %d\n", getMax(t));
    printf("Min: %d\n", getMin(t));
    return ;
}
