项目十一练习2

题目：

某无线通信设备ODU设备, 具有以下功能：

• 查看发射功率, 设置发射功率
• 查看发射频率, 设置发射频率
• 查看带宽, 修改带宽
• 查看设备概述(各指标的值)

后来对该产品做了升级, 研发了ODU330产品，
这个产品, 新增加了以下功能:

• 查看当前的误码率
• 查看误码率告警门限
• 设置误码率告警门限

代码实现：

1. ODU类

头文件

#pragma once
#include <string>

using namespace std;

class ODU
{
public:
	ODU();
	ODU(float transmissionPower, float transmissionFrequency, float bandwidth);

	void setTransmissionPower(float transmissionPower);
	void setTransmissonFrequency(float transmissonFrequency);
	void setBandwidth(float bandwidth);

	float getTransmissionPower() const;
	float getTransmissonFrequency() const;
	float getBandwidth() const;
	string description() const;

protected:
	float transmissionPower;		//发射功率
	float transmissonFrequency;		//发射频率
	float bandwidth;				//带宽

};

实现方法

#include <sstream>
#include "ODU.h"

ODU::ODU()
{
	transmissionPower = 0.0;
	transmissonFrequency = 0.0;
	bandwidth = 0.0;
}

ODU::ODU(float transmissionPower, float transmissionFrequency, float bandwidth)
{
	this->transmissionPower = transmissionPower;
	this->transmissonFrequency = transmissionFrequency;
	this->bandwidth = bandwidth;
}

void ODU::setTransmissionPower(float transmissionPower)
{
	this->transmissionPower = transmissionPower;
}

void ODU::setTransmissonFrequency(float transmissonFrequency)
{
	this->transmissonFrequency = transmissonFrequency;
}

void ODU::setBandwidth(float bandwidth)
{
	this->bandwidth = bandwidth;
}

float ODU::getTransmissionPower() const
{
	return transmissionPower;
}

float ODU::getTransmissonFrequency() const
{
	return transmissonFrequency;
}

float ODU::getBandwidth() const
{
	return bandwidth;
}

string ODU::description() const
{
	stringstream ret;
	ret << "OCU的发射功率是: " << transmissionPower << " 发射频率是: " << transmissonFrequency << " 带宽是: " << bandwidth;

	return ret.str();
}

2. ODU330类

头文件

#pragma once
#include <sstream>
#include "ODU.h"

class OUD330 : public ODU
{
public:
	OUD330(float transmissionPower, float transmissionFrequency, float bandwidth, float bar, int alarmThreshold);

	void setAlarmThreshold();

	float getBar() const;
	int getAlarmThreshold() const;
	string description() const;

private:
	float bar;				//误码率
	int alarmThreshold;		//告警门限
};

方法实现

#include "OUD330.h"

OUD330::OUD330(float transmissionPower, float transmissionFrequency, float bandwidth, float bar, int alarmThreshold):
	ODU(transmissionPower, transmissionFrequency, bandwidth)
{
	this->bar = bar;
	this->alarmThreshold = alarmThreshold;
}

void OUD330::setAlarmThreshold()
{
}

float OUD330::getBar() const
{
	return bar;
}

int OUD330::getAlarmThreshold() const
{
	return alarmThreshold;
}

string OUD330::description() const{
	stringstream ret;
	ret << "OCU330的发射功率是: " << transmissionPower << " 发射频率是: " << transmissonFrequency << " 带宽是: " << bandwidth
		<< " 误码率：" << bar << " 告警门限：" << alarmThreshold;

	return ret.str();
}

调用

#include <iostream>
#include "ODU.h"
#include "ODU330.h"

int main(){
	ODU o1(1000.5,300.12,40);
	ODU  O2;
	
	O2.setTransmissionPower(2019.22);
	O2.setTransmissonFrequency(2021.05);
	O2.setBandwidth(21);

	cout << o1.description() << endl;
	cout << O2.description() << endl;

	OUD330 odu(1000.53,230.71,23,0.000005,3);
	OUD330 odu2;

	odu2.setTransmissionPower(1998.03);
	odu2.setTransmissonFrequency(1997.12);
	odu2.setBandwidth(25);
	odu2.setAlarmThreshold(20);

	cout << odu.description() << endl;
	cout << odu2.description() << endl;

	return 0;
}
