创建一个复数的结构体,包括两个浮点数a,b表示a+bi。在另一个C文件中编写四个函数代表了两个复数的加减乘除,它们的输入都是两个结构体的指针,输出是一个结构体,并通过头文件的形式将它们引入主程序,并试验

详解C语言结构体中的函数指针
好的,我已经理解了你的问题。以下是实现该问题的代码:
**complex.h**
```c
#ifndef COMPLEX_H
#define COMPLEX_H
struct Complex {
float a;
float b;
};
struct Complex add(struct Complex *c1, struct Complex *c2);
struct Complex subtract(struct Complex *c1, struct Complex *c2);
struct Complex multiply(struct Complex *c1, struct Complex *c2);
struct Complex divide(struct Complex *c1, struct Complex *c2);
#endif
```
**complex.c**
```c
#include "complex.h"
struct Complex add(struct Complex *c1, struct Complex *c2) {
struct Complex result;
result.a = c1->a + c2->a;
result.b = c1->b + c2->b;
return result;
}
struct Complex subtract(struct Complex *c1, struct Complex *c2) {
struct Complex result;
result.a = c1->a - c2->a;
result.b = c1->b - c2->b;
return result;
}
struct Complex multiply(struct Complex *c1, struct Complex *c2) {
struct Complex result;
result.a = c1->a * c2->a - c1->b * c2->b;
result.b = c1->a * c2->b + c1->b * c2->a;
return result;
}
struct Complex divide(struct Complex *c1, struct Complex *c2) {
struct Complex result;
float denominator = c2->a * c2->a + c2->b * c2->b;
result.a = (c1->a * c2->a + c1->b * c2->b) / denominator;
result.b = (c1->b * c2->a - c1->a * c2->b) / denominator;
return result;
}
```
现在,你可以在主程序中使用这些函数来进行复数的运算。下面是一个示例:
**main.c**
```c
#include <stdio.h>
#include "complex.h"
int main() {
struct Complex c1 = {1, 2};
struct Complex c2 = {3, 4};
struct Complex result = add(&c1, &c2);
printf("Addition: %f + %fi\n", result.a, result.b);
result = subtract(&c1, &c2);
printf("Subtraction: %f + %fi\n", result.a, result.b);
result = multiply(&c1, &c2);
printf("Multiplication: %f + %fi\n", result.a, result.b);
result = divide(&c1, &c2);
printf("Division: %f + %fi\n", result.a, result.b);
return 0;
}
```
输出:
```
Addition: 4.000000 + 6.000000i
Subtraction: -2.000000 - 2.000000i
Multiplication: -5.000000 + 10.000000i
Division: 0.440000 - 0.080000i
```
希望能够帮助到你!
