rational.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 "Rational.h"

void initRational(Rational *pr){
	pr->num=1;
	pr->denom=1;
}
Rational multiplyRational(Rational *pr1, Rational *pr2){
	Rational result;
	result.num=pr1->num*pr2->num;
	result.denom=pr1->denom*pr2->denom;
	return result;
}

Rational subRational(Rational *pr1, Rational *pr2){
	Rational result;
	result.denom=pr1->denom*pr2->denom;
	result.num=pr1->num*pr2->denom - pr1->denom*pr2->num;
	return result;
}

Rational addRational(Rational *pr1, Rational *pr2){
	Rational result;
	result.denom=pr1->denom*pr2->denom;
	result.num=pr1->num*pr2->denom + pr1->denom*pr2->num;
	return result;
}

void printRational(Rational *pr){
	printf("%d/%d", pr->num, pr->denom);
}
