Complete the
HINT: Remember to open the file and check if that open command succeseded using the fail() method. When reading lines from a file, it makes sense to read all parts in the while condition.
infile.open(filename);
while(infile >> name >> value >> theRest) {
// Process input
}
infile.close();
If the program files to open the file:
Enter the name of the file to be analyzed:amzn.csv
File amzn.csv cannot be opened.
code:
#include <iostream>
#include <limits>
#include <fstream>
using namespace std;
//Todo: declare your functions here.
int main()
{
ifstream infile;
char fileName[256];
cout <<"Enter the name of the file to be analyzed:";
cin >> fileName;
// TODO: Open the filename and test that it was successful
// Used to read in te date, price and the rest.
double price;
string date, junk;
// Going to store the date of the high price and low price
string lowDate, highDate;
// Going to store the high price and low price.
double high=numeric_limits<double>::min(), low=numeric_limits<double>::max();
cout.precision(2);
cout.setf(ios::fixed);
// TODO: Implement a loop that reads line by line from input.
// TODO: A line has the date, the price and the rest (use junk)
// TODO: Stop reading on end of input.
while ( true ) {
cout << date << " " << price << endl;
