错误1错误C4700：C ++中未初始化的本地变量“rate”和“hours”

问题描述

我是编程的初学者。我写一个C ++程序，用户将他们的工资率和工作时间，然后计算工资和工作时间然后显示它。我完成程序有两个错误，我试图修复，但我仍然不能弄清楚修复它。错误和我的代码如下。有人可以帮助我，告诉我如何解决？我使用的是MSVS Express 2013。

I am a beginner to programming. I'm writing a C++ program that a user will their pay rate and the hours worked, and then calculate the pay and hours worked then display it. I finish the program the there are two errors that I tried to fix but I still can't figure out to fix it. The errors and my code is below. Can someone help me and tell me how to fix? I'm using MSVS Express 2013.

错误：

Error   1   error C4700: uninitialized local variable 'hours'

Error   2   error C4700: uninitialized local variable 'rate'

（ displayWeekly（rate，hours）; ）错误

代码：

#include "stdafx.h"

#include<iostream>

using namespace std;
void displayWeekly(double rate, int hours);
double getRate();
int getHours();

int main()
{

double rate; 

int hours;

displayWeekly(rate, hours);

double getRate();
int getHours();

rate = getRate();
hours = getHours();

system("pause");
return 0;
}

void displayWeekly(double rate, int hours)
{
double weekPay;
weekPay = rate * hours;
cout << "Weekly pay is " << weekPay << endl;
}

double getRate()
{
double rate;
cout << "Enter your Hourly rate in the Dollars and Cents = ";
cin >> rate;
return rate;
}

int getHours()
{
int time;
cout << "Please Enter in the Hours you worked" << endl;
cout << "You must Enter a whole Number = ";
cin >> time;
return time;
}

推荐答案

像这样：

int main()
{
    double rate;
    int hours;

    //double getRate(); --> where do you think the return value is stored to?
    //int getHours();   --> 

    rate = getRate();
    hours = getHours();

    displayWeekly(rate, hours);  // --> has to go after you put values to rate & hours

    system("pause");
    return 0;
}
