復數(shù)的基本運算(C語言)

1、復數(shù)的基本運算(c語言)#include<>#include<>typedef struct fushu/抽象數(shù)據類型定義float real;/數(shù)據對象float image;fushu;fushu complexnumberinput(float a,float b)/構造二元組fushu c;=a;/實部=b;/虛部return(c);fushu complexnumberadd(fushu c1,fushu c2)/求和運算fushu sum;=+;=+;return (sum);fushu complexnumbersub(fushu c1,fushu c2)

2、/求差運算fushu sub;=return (sub);fushu complexnumbermul(fushu c1,fushu c2)/求積運算fushu mul;=*=*+*;return (mul);fushu complexnumberdiv(fushu c1,fushu c2)/求商運算 fushu div; float d1,d2,d3,d4; d1=*+*; d2=*+*; d3=* d4=*+*; if(d2!=0&&d4!=0) =d1/d2; =d3/d4; return(div); else =0; =0; return(div); void comp

3、lexnumberoutput(fushu c)/輸出運算結果if=&&= printf("0n"); if=&&!= printf("%fin",;if!=&&= printf("%fn",;if!=&&!= printf("%f+(%fi)n",;void main()/主函數(shù)int choice;int k;float a1,a2,b1,b2;struct fushu c1,c2,sum,sub,mult,div;printf("歡迎進

4、行復數(shù)的基本代數(shù)運算n");printf("1: 復數(shù)加法運算n");printf("2: 復數(shù)減法運算n"); printf("3: 復數(shù)乘法運算n");printf("4: 復數(shù)除法運算n");printf("0: 推出系統(tǒng)n");printf("請分別輸入第一個復數(shù)的實部和虛部: ");scanf("%f%f",&a1,&b1);c1 = complexnumberinput(a1,b1);printf("第一個復

5、數(shù)為: ");complexnumberoutput(c1);printf("請分別輸入第二個復數(shù)的實部和虛部: ");scanf("%f%f",&a2,&b2);c2 = complexnumberinput(a2,b2);printf("第二個復數(shù)為: ");complexnumberoutput(c2);for(;)printf("請輸入你選擇的功能: ");scanf("%d",&choice);switch(choice)case 0:exit(0);

6、break;case 1:sum = complexnumberadd(c1,c2);printf("求和后結果為: ");complexnumberoutput(sum);break;case 2:sub = complexnumbersub(c1,c2);printf("求差后結果為: ");complexnumberoutput(sub);break;case 3:mult = complexnumbermul(c1,c2);printf("求積后結果為: ");complexnumberoutput(mult );break;case 4:div=complexnumberdiv(c1,c2); if!=0&&!=0) printf("求商后結果: &qu
