使用c语言编程，和数能表示1~23的5个正整数 已知五个互不相同的正整数之和为23，且从这五个数中挑选若干个加起来可以表示从1 到23之内的全部自然数，问这五个数都是什么？ **输入格式要求：提示信息："There are following possible result:\n" **输出格式要求："[%d]:%d,%d,%d,%d,%d\n"

以下是使用 C 语言编写的代码实现：

#include <stdio.h>

int main() {
    printf("There are following possible result:\n");
    int a, b, c, d, e;
    int count = 0;
    for (a = 1; a <= 23; a++) {
        for (b = a + 1; b <= 23; b++) {
            for (c = b + 1; c <= 23; c++) {
                for (d = c + 1; d <= 23; d++) {
                    for (e = d + 1; e <= 23; e++) {
                        if (a + b + c + d + e == 23 &&
                            a + b + c >= 1 && a + b + d >= 2 && a + b + e >= 3 &&
                            a + c + d >= 4 && a + c + e >= 5 && a + d + e >= 6 &&
                            b + c + d >= 7 && b + c + e >= 8 && b + d + e >= 9 &&
                            c + d + e >= 10) {
                                printf("[%d]:%d,%d,%d,%d,%d\n", ++count, a, b, c, d, e);
                        }
                    }
                }
            }
        }
    }
    return 0;
}

代码中使用了五重循环来枚举所有满足条件的五个正整数，然后依次判断是否满足方程组。如果满足，就输出这五个数。

输出结果如下：
