Question

Write a program to help a travelling sales person keep up with their daily mileage driven for business. In your main method, the program should first ask the user how many days of mileage they want to enter and then collect the user input for each day's miles, storing the values entered in an appropriately sized array.

Answer 1

Answer:

The programming language is not stated;

The program written in C++ is as follows (See Explanation Section for detailed explanation);

#include<iostream>

using namespace std;

int main()

{

 int numdays;

 cout<<"Number of days of mileage: ";

 cin>>numdays;

 int miles[numdays];

for(int i=0;i<numdays;i++)

{

 cout<<"Miles traveled on day "<<i+1<<": ";

 cin>>miles[i];

}

 int total = 0;

 for(int i=0;i<numdays;i++)

{

 total+=miles[i];

}

cout<<"Total mileage traveled: "<<total;

 return 0;

}

Explanation:

This line declares the number of days of mileage

 int numdays;

This line prompts user for days of mileage

 cout<<"Number of days of mileage: ";

This line accepts input from the traveler for days of mileage

 cin>>numdays;

This line creates an array

 int miles[numdays];

The italicized is an iteration that collects the user input for each day

for(int i=0;i<numdays;i++)

{

 cout<<"Miles traveled on day "<<i+1<<": ";

 cin>>miles[i];

}

This line initializes variable to 0

 int total = 0;

The italicized is an iteration that adds up the mileage traveled by the traveler each day  

 for(int i=0;i<numdays;i++)

{

 total+=miles[i];

}

This line prints the total miles traveled

cout<<"Total mileage traveled: "<<total;
