Question

Write in C++

Example

Enter number of miles travelled

12340

Enter number of hours in trip

460

file.txt

Miles: 12340

Hours: 460

MPH: 26.83

Question:

Write a program that does the following things:

1 ) Ask the user for number of miles travelled (should be in getData function and number of hours in trip (should be in getData function)

[Note: Use reference parameters to have access to these values in main]

2 ) Calculate the miles per hour(MPH) for the trip (should be in main)

3 ) write the miles, hours and MPH to a text file (should be in writeFile function)

[Note: Use reference parameter for writer]

Here are the functions you need       

Function name | Parameters                       | Return Type   

getData |  miles, hours   | void

writeFile | writer, miles, hours, MPH | void

Answer 1

#include<iostream>
#include <fstream>
using namespace std;
void getData(int &miles,int &hours ){
  //reading the data from the user for hours and miles
        cout<<"Enter number of miles travelled\n";
        cin>>miles;
        cout<<"Enter number of hours in trip\n";
        cin>>hours;
}
void writeFile(ofstream &myfile,int miles,int hours,double mph){
  //writing the miles and hours and MPH to file
        myfile<<"Miles: "<<miles<< endl;
        myfile<<"Hours: "<<hours<< endl;
        myfile<<"MPH: "<<mph<< endl;
}
int main(){
        int miles,hours;
  //getting the user data
        getData(miles,hours);
  //calculating the mph
        double mph = miles/(double)(hours);
  //opening the file
        ofstream myfile("file.txt");
  //writing to the file
        writeFile(myfile,miles,hours,mph);
        myfile.close();

}
