1- The program that follows will display a file called myfile.txt containing 6 records with two fields each.

The data is as follows.

420 violet

470 blue

500 cyan

530 green

580 yellow

620 orange

700 red

The numbers refer to the wavelength, measured in nanometers, of each of the colors shown to the right.

[code]

// DisplayLightWavelength.cpp

#include

#include

#include

using namespace std;

int main() {

//reading from a file

//create file objects

ifstreaminfile;

//need two variables to receive the data

int lambda;

string color;

//associate them with a file

infile.open("myfile.txt");

//make sure the file exists

if (!infile.is_open())//file not found

cout

else

{

//read first value

Infile>> lambda;

while (!infile.eof())

{

//read the rest of the line

infile>> color;

//print what we just read

cout

//read the beginning of the next data record

infile>> lambda;

}

infile.close();

}

return 0;

}

[/code]

When the program is run, the output is FROM myfile.txt:

The wavelength of "violet" is 420 nanometers

The wavelength of "blue" is 470 nanometers

The wavelength of "cyan" is 500 nanometers

The wavelength of "green" is 530 nanometers

The wavelength of "yellow" is 580 nanometers

The wavelength of "orange" is 620 nanometers

The wavelength of "red" is 700 nanometers

I need help witha program

which takes the contents of myfile.txt,

and creates a new file called: results.txt

results.txt is a textfilewhich has the format:

color frequency

color simply refers to the color of the record being processed.

frequency refers to the frequency (given in TeraHertz[THz]) of the color.

Remember that frequency = SpeedOfLight/WaveLength.

Note that although the WaveLengthwas given as an integer, the frequency will need to be given as a double.

Use the following value for the speed of light: 299,792.46 km/sec.
