一个有理数（Rational）是由一个分子（numerator）和分母（denominator)组成的a/b形式的数。编写程序实现有理数如下功能： 包括三个文件Rational.h，Rational.cpp(30分),TestRationalClass .cpp(20分)。 Class Rational { Public: Rational(); Rational(long numerator,long denominator); //最简分式 Long getNumerator(); Long getDenominator(); Rational add(Rational &secondRational); Rational divide(Rational &secondRational); Int compareTo(Rational &secondRational); Bool equals(Rational &secondRational); Int intValue(); Double doubleValue(); String toString(); //分为分母=1与a/b的方式；提示：使用itoa()与strcat()函数 Private: Long numerator; Long denominator； Static long gcd(long n, long d); };

private); Rational subtract(Rational private); Rational multiply(Rational); Rational divide(Rational private); void printRational(); Private: Long numerator; Long denominator; };这是一个可以实现有理数功能的C++程序：Rational.h：#ifndef RATIONAL_H
#define RATIONAL_Hclass Rational
{
public:
Rational(); //默认构造函数
Rational(long numerator, long denominator); //最简分式
long getNumerator();
long getDenominator();
Rational add(Rational private);
Rational subtract(Rational private);
Rational multiply(Rational private);
Rational divide(Rational private);
void printRational();
private:
long numerator;
long denominator;
};#endif //RATIONAL_H

写一个C++代码：一个有理想（Rational）是由一个分子（numerator）和分母（denominator)组成的a/b形式的数。编写程序实现有理数如下功能： 包括三个文件Rational.h，Rational.cpp(30分),TestRationalClass .cpp(20分)。

#include <iostream>
using namespace std;//Rational.h
class Rational {
private:
int numerator;
int denominator;

public:

Rational有理数（分数）1.分子numerator,分母denominator 2.构造方法2个3.生成getter和setter方法4.求两个分数的和5.ToString方法"1/2"

1. 分子numerator, 分母denominator

public class Rational {
    private int numerator;
    private int denominator;

    // 构造方法和其他方法略
}

2. 构造方法2个

public Rational(int numerator, int denominator) {
    this.numerator = numerator;
    this.denominator = denominator;
}

public Rational(int numerator) {
    this.numerator = numerator;
    this.denominator = 1;
}

3. 生成getter和setter方法

public int getNumerator() {
    return numerator;
}

public void setNumerator(int numerator) {
    this.numerator = numerator;
}

public int getDenominator() {
    return denominator;
}

public void setDenominator(int denominator) {
    this.denominator = denominator;
}

4. 求两个分数的和

public Rational add(Rational other) {
    int newNumerator = this.numerator * other.denominator + other.numerator * this.denominator;
    int newDenominator = this.denominator * other.denominator;
    return new Rational(newNumerator, newDenominator);
}

5. ToString方法"1/2"

@Override
public String toString() {
    return numerator + "/" + denominator;
}
