编写一个C语言小程序，验证对于多个数的加（减）运算，定点数的运算结果与运算顺序无关（即使是含义运算溢出），而浮点数的运算结果可能与运算顺序有关

#include <stdio.h>

int main() {
// 定点数的运算
int a = 10, b = 20, c = 30, d = 40;
int result1 = a + b + c + d;
int result2 = a + c + b + d;
printf("Fixed-point addition result1: %d\n", result1);
printf("Fixed-point addition result2: %d\n", result2);
int result3 = a - b - c - d;
int result4 = a - c - b - d;
printf("Fixed-point subtraction result3: %d\n", result3);
printf("Fixed-point subtraction result4: %d\n", result4);

// 浮点数的运算
float x = 1.0, y = 2.0, z = 3.0, w = 4.0;
float result5 = x + y + z + w;
float result6 = x + z + y + w;
printf("Floating-point addition result5: %f\n", result5);
printf("Floating-point addition result6: %f\n", result6);
float result7 = x - y - z - w;
float result8 = x - z - y - w;
printf("Floating-point subtraction result7: %f\n", result7);
printf("Floating-point subtraction result8: %f\n", result8);

return 0;
}
