C语言实现复数抽象数据类型及应用示例

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

typedef struct { float real; float imag; } Complex;

void Create(float x, float y, Complex* z) { z->real = x; z->imag = y; }

void Add(Complex z1, Complex z2, Complex* sum) { sum->real = z1.real + z2.real; sum->imag = z1.imag + z2.imag; }

void Subtract(Complex z1, Complex z2, Complex* difference) { difference->real = z1.real - z2.real; difference->imag = z1.imag - z2.imag; }

void Multiply(Complex z1, Complex z2, Complex* product) { product->real = z1.real * z2.real - z1.imag * z2.imag; product->imag = z1.real * z2.imag + z2.real * z1.imag; }

void Get_RealPart(Complex z, float* e) { *e = z.real; }

void Get_ImagPart(Complex z, float* e) { *e = z.imag; }

int main() { Complex z1, z2, sum, difference, product; float realPart, imagPart;

Create(2, 3, &z1);
Create(4, 5, &z2);

Add(z1, z2, &sum);
