Question

Trying to read from a file like this:
Brand: Price: Amount:
Toyota 2000 4
Honda 3000 5
Ford 4000 6
Audi 5000 7

And calculate the total value of all the cars, as well as the average price for each car and output it to a file. Help is greatly appreciated; the first working program gets full points.

#include<fstream.h>
#include<stdlib.h>
#include<string>
using namespace std;
int main()
{
int n=4, i=0, j=0;
float price[n],amount[n], Value[n];
string Title[3],carbrand[4];
float Totalvalue=0;


//************************************
ifstream file("car.txt");

if(!open)
{
cout<<" Could not open ";
exit(-1);
}
else
{
for (i=0;i<4;i++)
{
file>>Title[i];
cout<<Title[i]<<" ";
}
cout<<" ";
for (i=0;i<4;i++)
{
cin>>carbrand[i]>>price[i]>>amount[i];
cout<<carbrand[i]<<" "<<price[i]<<" "<<amount[i]<<" "<<endl;
}
}
file.close();

//************************
Totalvalue=0;
for(i=1;i<4;i++)
{
Value[i]=price[i]*amount[i];
Totalvalue=Totalvalue+Value[i];
}
//*************************************
ofstream Write("Summary.txt");

if(!Write)
{
cout<<" Could not open ";
exit(-1);
}
else
{

for(i=0;i<4;i++);
{
Summary<<carbrand[i]<<" ";
Write<<price[i] <<" ";
}
Summary<<" ";
Summary<<Title[0]<<" ";




Write<<" ";
Write<<Title[2]<<" ";
for(i=1;i<5;i++)
{
Write<<amount[i]<<" ";
}
Write<<" ";
Write<<"Value"<<" ";
for(j=1;j<5;j++);
{
Write<<Value[i]<<" ";
}
Write<<" ";

Write<<"The Total Value of all these cars is: ";
Write<<Totalvalue<<endl;
}
return 0;

Explanation / Answer

please rate - thanks

hope this is good. you just gave code, didn't explain what it's supposed to do

#include <iostream>
#include<fstream>
#include<cstdlib>
#include<string>
using namespace std;
int main()
{
int n=4, i=0, j=0;
float price[n],amount[n], Value[n];
string Title[3],carbrand[4];
float Totalvalue=0;


//************************************
ifstream file;
file.open("car.txt");

if(!file)
{
cout<<" Could not open ";
exit(-1);
}
else
{
for (i=0;i<3;i++)
{
file>>Title[i];
cout<<Title[i]<<" ";
}
cout<<" ";
for (i=0;i<4;i++)
{
file>>carbrand[i]>>price[i]>>amount[i];
cout<<carbrand[i]<<" "<<price[i]<<" "<<amount[i]<<" "<<endl;
}
}
file.close();

//************************
Totalvalue=0;
for(i=0;i<4;i++)
{
Value[i]=price[i]*amount[i];
Totalvalue=Totalvalue+Value[i];
}
//*************************************
ofstream Summary;
Summary.open("Summary.txt");

if(!Summary)
{
cout<<" Could not open ";
exit(-1);
}
else
{
for(i=0;i<3;i++)
   Summary<<Title[i]<<" ";
Summary<<"Value ";  
for(i=0;i<4;i++)
   {
    Summary<<carbrand[i]<<" ";
    Summary<<price[i] <<" ";
    Summary<<amount[i]<<" "<<Value[i];
    Summary<<" ";
    }


Summary<<"The Total Value of all these cars is: $";
Summary<<Totalvalue<<endl;
}
system("pause");
return 0;
}
