Trying to debug the following code in c++, if I could get the solution along with an explanation that would be great.

The error I keep getting is: no suitable conversion function from "std::basic_istream>" to "bool" exists for the 3rd to last line "bool foundData = someFile >> city >> rain;"

This is the code:

// This program displays a table of July rainfall totals for several

// American cities. It calls a function to read the data from a file

// one line at a time. The data values are stored in reference

// parameters so they can be seen and used by the main function.

#include

#include

#include

#include

using namespace std;

// Function prototype

bool readData(ifstream &someFile, string city, double rain);

int main()

{

ifstream inputFile;

string city;

double inchesOfRain;

// Display table headings

cout << "July Rainfall Totals for Selected Cities ";

cout << " City Inches ";

cout << "________________ ";

// Open the data file

inputFile.open("weather.dat");

if (inputFile.fail())

cout << "Error opening data file. ";

else

{ // Call the readData function

// Execute the loop as long as it found and read data

while (readData(inputFile, city, inchesOfRain) == true)

{

cout << setw(11) << left << city;

cout << fixed << showpoint << setprecision(2)

<< inchesOfRain << endl;

}

inputFile.close();

}

return 0;

}
