复数的基本运算

1、#in clude#in cludetypedef struct fushu/抽象数据类型定义float real;/数据对象float image;fushu;fushu ComplexNumberlnput(float a,float b) 构造二元组 fushu c;c.real=a;/ 实部c.image=b;/ 虚部return(c);fushu ComplexNumberAdd(fushu c1,fushu c2)/ 求和运算 fushu sum;sum.real=c1.real+c2.real;sum.image=c1.image+c2.image;return (sum);fu

2、shu ComplexNumberSub(fushu c1,fushu c2)/ 求差运算 fushu sub;sub.real=c1.real-c2.real;sub.image=c1.image-c2.image;return (sub);fushu ComplexNumberMul(fushu c1,fushu c2)/ 求积运算fushu Mul;Mul.real=c1.real*c2.real-c1.image*c2.image;Mul.image=c1.real*c2.image+c1.image*c2.real; return (Mul);fushu ComplexNumberD

3、iv(fushu c1,fushu c2)/ 求商运算 fushu div;float d1,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=0;return(div

4、);void ComplexNumberOutput(fushu c)/if(c.real=0.0&c.image=0.0)if(c.real=0.0&c.image!=0.0)if(c.real!=0.0&c.image=0.0)if(c.real!=0.0&c.image!=0.0)void main() 主函数int choice;输出运算结果prin tf(0n);prin tf(%fin,c.image);prin tf(%fn,c.real);prin tf(%f+(%fi)n,c.real,c.image)int k;float a1,a2,b1,b2;struct fushu

5、c1,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:推出系统 n);printf(请分别输入第一个复数的实部和虚部：”);scan f(%f%f,&a1,&b1);c1 = ComplexNumberI nput(a1,b1); printf(第一个复数为:);ComplexNumberOutput(c1);printf（请分别输入第二个复数的实部和虚部：”）;scan f(%f%f,&a2,&

6、b2);c2 = ComplexNumberl nput(a2,b2); printf(第二个复数为:”);ComplexNumberOutput(c2);for(;)printf(请输入你选择的功能:);scan f(%d, &choice);switch(choice)case 0:exit(0);break;case 1:sum = ComplexNumberAdd(c1,c2);printf(求和后结果为:);ComplexNumberOutput(sum);break;case 2:sub = ComplexNumberSub(c1,c2);printf(求差后结果为：”)；ComplexNumberOutput(sub);break;case 3:mult = ComplexNumberMul(c1,c2);printf(求积后结果为:);ComplexNumberOutput(mult );break;case 4:div=ComplexNumberDiv(c1,c2);if(div.real!=O
