complex.c

C的有理數的複數算法 一般資訊學院要求 一般來說會是考題之一

#include <stdio.h>
#include "Complex.h"

void initComplex(Complex * pc){
	initRational(&pc->real);
	initRational(&pc->imag);
}

Complex multiplyComplex(Complex *pc1, Complex *pc2){
	Complex result;
	Rational r1, r2;
	
	r1=multiplyRational(&pc1->real, &pc2->real);
	r2=multiplyRational(&pc1->imag, &pc2->imag);
	result.real=subRational(&r1, 	&r2);

	r1=multiplyRational(&pc1->real, &pc2->imag);
	r2=multiplyRational(&pc1->imag, &pc2->real);
	result.imag=addRational(&r1, &r2);

	return result;
}

void printComplex(Complex *pc){
	//printf("(%d,%d)", pc->real,pc->imag);
	printf("(");
	printRational(&pc->real);
	printf(", ");
	printRational(&pc->imag);
	printf(")");
