C语言复数的加减及输出结构体
短信预约 -IT技能 免费直播动态提醒
一、
#include<stdio.h>
typedef struct complex
{
int real; //实部
int imag; //虚部
}complex;
complex complexadd(complex x,complex y)
{
complex sum;
sum.real = x.real + y.real;
sum.imag = x.imag + y.imag;
return sum;
}
complex complexsub(complex x,complex y)
{
complex sum;
sum.real = x.real - y.real;
sum.imag = x.imag - y.imag;
return sum;
}
void printfcomplex(complex x)
{
printf("%d",x.real);
if(x.imag > 0)
{
printf("+");
}
printf("%d\n",x.imag);
}
int main()
{
complex f1 = {3,-5};
complex f2 = {-5,8};
printfcomplex(f1);
printfcomplex(f2);
complex f3 = complexadd(f1,f2);
printfcomplex(complexadd(f1,f2));
printfcomplex(f3);
printfcomplex(complexsub(f1,f2));
return 0;
}
二、分文件
complex.c
#include<stdio.h>
#include"complex.h"
complex complexadd(complex x,complex y)
{
complex sum;
sum.real = x.real + y.real;
sum.imag = x.imag + y.imag;
return sum;
}
complex complexsub(complex x,complex y)
{
complex sum;
sum.real = x.real - y.real;
sum.imag = x.imag - y.imag;
return sum;
}
void printfcomplex(complex x)
{
printf("%d",x.real);
if(x.imag > 0)
{
printf("+");
}
printf("%di\n",x.imag);
}main.c
#include<stdio.h>
#include"complex.h" // complex 头文件
int main()
{
complex f1 = {3,-5}; // 结构体初始化
complex f2 = {-5,8};
printfcomplex(f1); // 打印复数
printfcomplex(f2);
complex f3 = complexadd(f1,f2);
printfcomplex(complexadd(f1,f2));
printfcomplex(f3);
printfcomplex(complexsub(f1,f2));
return 0;
}complex.h
#ifndef __COMPLEX_H__
#define __COMPLEX_H__
// 类型声明
typedef struct complex
{
int real; //实部
int imag; //虚部
}complex;
complex complexadd(complex x,complex y);
complex complexsub(complex x,complex y);
void printfcomplex(complex x);
