Question

Write a program that inputs a wavelength value from the user and decides the color based on the following intervals:
Color Wavelength (nm)
Violet 380 to less than 450
Blue 450 to less than 495
Green 495 to less than 570
Yellow 570 to less than 590
Orange 590 to less than 620
Red
620 to 750
If the wavelength is greater than or equal to 750 or less than 380, the program should print It is not a visible color.
Sample output1:
Please enter a wavelength value: 567
Green.
Sample output2:
Please enter a wavelength value: 300
It is not a visible light.
Sample output3:
Please enter a wavelength value: 890
It is not a visible light.

Step 1

#include <iostream>
using namespace std;
int main()
{
    cout<<"Please enter a wavelength value : ";//message to the user.
    int wavelen;
    cin>>wavelen; //taking wavelength as input from the user.
    if(wavelen>750||wavelen<380)   //if wavelength<380 or wavelength>750 Not 
        //a valid Wavelength
        cout<<"It is not a visible light.\n";
     if(wavelen>=380&&wavelen<450)
        cout<<"Violet\n";              //if wavelength is in between 380 and less than 450
     if(wavelen>=450&&wavelen<495)
        cout<<"Blue\n";                 //if wavelength is in between 380 and less than 450
     if(wavelen>=495&&wavelen<570)
        cout<<"Green\n";              //if wavelength is in between 465 and less than 570
     if(wavelen>=570&&wavelen<590)
        cout<<"Yellow\n";            //if wavelength is in between 570 and less than 590
     if(wavelen>=590&&wavelen<620)
        cout<<"Orange\n";   //if wavelength is in between 590 and less than 620
     if(wavelen>=620&&wavelen<750)
        cout<<"Red\n";         //if wavelength is in between 620 and less than 750
