1、构造二元组求和运算#include<stdio.h> #include<stdlib.h>typedefstructfushu/ 抽象数据类型定义 floatreal;/ 数据对象floatimage;fushu; fushuComplexNumberInput(floata,floatb)/fushuc;c.real=a;/ 实部c.image=b;/ 虚部return(c);fushuComplexNumberAdd(fushuc1,fushuc2)/ fushusum;sum.real=c1.real+c2.real;sum.image=c1.image+c2.i
2、mage;return(sum);fushuComplexNumberSub(fushuc1,fushuc2)/ 求差运算fushusub;sub.real=c1.real-c2.real;sub.image=c1.image-c2.image;return(sub);fushuComplexNumberMul(fushuc1,fushuc2)/ 求积运算fushuMul;Mul.real=c1.real*c2.real-c1.image*c2.image;Mul.image=c1.real*c2.image+c1.image*c2.real; return(Mul);fushuComplex
3、NumberDiv(fushuc1,fushuc2)/ 求商运算fushudiv;floatd1,d2,d3,d4;d1=c1.real*c2.real+c1.image*c2.image;d2=c2.real*c2.real+c2.image*c2.image;d3=c1.image*c2.real-c1.real*c2.image;d4=c2.real*c2.real+c2.image*c2.image;if(d2!=0&&d4!=0) div.real=d1/d2; div.image=d3/d4; return(div);elsediv.real=0;div.image
4、=0; return(div); voidComplexNumberOutput(fushuc)/ 输出运算结果 if(c.real=0.0&&c.image=0.0)printf("0n");if(c.real=0.0&&c.image!=0.0)printf("%fin",c.image)Jif(c.real!=0.0&&c.image=0.0)printf("%fn",c.real);if(c.real!=0.0&&c.image!=0.0)printf("
5、;%f+(%fi)n",c.r eal,c.image);voidmain（）/ 主函数intchoice;intk;floata1,a2,b1,b2; structfushuc1,c2,sum,sub,mult,div;printf（" 欢迎进行复数的基本代数运算 n"）;printf（"1: 复数加法运算 n"）;printf（"2: 复数减法运算 n"）;printf（"3: 复数乘法运算 n"）;printf（"4: 复数除法运算 n"）;printf（"0: 推出系
