Help please:

Write a program that translates a TV channel (1 through 10) in your area to its respective call sign. For example, in the New York metropolitan area, channel 2 translates to WCBS. If a channel is unused in your area, tell the user that this is the case.

Sample output from program:

Translate TV Channel Number to Call Sign

 

Enter channel number: 1

Channel 1 is undesignated in your area

 

Enter channel number: 2

Call sign for channel 2 is WCBS

 

Enter channel number: 6

Call sign for channel 6 is WRNNDT

lol what ?

[Aaaaaaaaa]

It is a programming question! If you don't know anything about programming no need to hurt your brains with this.

iknow programming but providing an answer to that is...well never mind. stop spamming the forums btw  

[Aaaaaaaaa]

I thought this was a helping site, and all you can think of is stop spamming. Smt

How is the data stored? Is it stored in a 2D array? 

 

What language btw?

I am not sure but i think its a work for registries or a database not a written program

Pseudocode: Although there are several valid ways to write the program, the following is an outline of one way to design the overall logic.

 

Declare variables for channel and call sign

Get channel number from user

Use appropriate decision structure to translate number to call sign

If number is valid in area

Print out translation

If not

Tell user this is the case

Well, I'm just going to assume they tell you what channel # corresponds to each network name... so: 

 

Create a 2D array, with the channel number in the first column and the name of the network in the second column. 

Get channel number. 

Find the channel number in the array. 

Print "Call sign for channel" +  ___ + "is" _____"

 

As for actually coding it...well, that depends on the language and how the channel numbers and network names are stored. 

[Aaaaaaaaa]

djdwosk97

The language used is C# comments. And the channel numbers are set up like this

Enter channel number: 1

Channel 1 is undesignated in your area

 

Enter channel number: 2

Call sign for channel 2 is WCBS

 

Enter channel number: 6

Call sign for channel 6 is WRNNDT

Every other channel has nothing its blank.

Well, I don't know C#, but how is the data actually stored--not whats the output supposed to be...Is it stored like that, or is it stored in an array...I cant imagine the data would be stored like that as thats a pain to work with.

 Yes! It is stored in array.

[79wjd]

 Yes! It is stored in array.

Okay, so if I was going to put the data into an array I would put channel 0 in array[0][0] and the name of channel zero in array[0][1], channel one in array[1][0] and the name in array[1][1] and so on....

 

In Java it would look something like this: 

System.out.println("Enter channel number: ");int channelNumber = TextIO.getlnInt(); //gets user input System.out.println("Call sign for channel " + channelNumber + " is " + array[channelNumber]);

Now, I'm assuming that if the channel doesn't exist then the contents of the array for that channel will be the channel number in the first column and "undesignated in your area" in the second column.

Okay! What about what comes ahead of that? Declaring the variables?

Well, im assuming the array has already been created. And you dont need to create any other variables (at least you dont in java or c++)

No!

[79wjd]

No!

well, how are you given the information then? The channel number and its associated name has to be in the program somehow. And since it would be stupid if the user had to enter that information, it has to be there before you compile it...so, how does it get there? Are you told what channel is related to what and you have to create the array with that information in it, or is it given to you.

 Yes we have to enter that information in Visual Studio. We have to enter in the information, write our own code with the hopes of achieving the output. This is the question given to me below, this is all the information I was given.

Requirements

Your mission: Write a program that translates a TV channel (1 through 10) in your area to its respective call sign. For example, in the New York metropolitan area, channel 2 translates to WCBS. If a channel is unused in your area, tell the user that this is the case.

Sample output from program:

Translate TV Channel Number to Call Sign

 

Enter channel number: 1

Channel 1 is undesignated in your area

 

Enter channel number: 2

Call sign for channel 2 is WCBS

 

Enter channel number: 6

Call sign for channel 6 is WRNNDT

 

Tips

Best practice: Put yourself in the place of the program. What steps would you personally need to perform in order to process a channel translation yourself? Write out those steps on paper as pseudocode and/or in Visual Studio as C# comments, and then implement them one by one, testing as you go. Remember to not write too much at one time. Always add and test functionality incrementally!

Declare variables for channel and call sign

Get channel number from user

[LukeTim]

Do you have to get the users area?

You could use a 2D array (or map)... Area on the Y axis, and Channel on the X axis. Then simply use the area and channel number to index the array/map and return the corresponding callsign.

Easy.

[Kiwi00000]

This is an very ugly solution, but I only had a few mins to chuck this together.

 

You could also use a switch statement and have a default case that says "I don't know this channel".

 

You might also want to add a looping function that allows the user to re-enter a number and get another channel name.

 

More information would be nice next time so we know how in depth your programming knowledge is.

 

Hope this helped.

static void Main(string[] args)        {            string[] channelNames = new string[10];            channelNames[0] = "AAAAAA";            channelNames[1] = "BBBBBB";            channelNames[2] = "CCCCCC";            channelNames[3] = "DDDDDD";            channelNames[4] = "EEEEEE";            channelNames[5] = "FFFFFF";            channelNames[6] = "GGGGGG";            channelNames[7] = "HHHHHH";            channelNames[8] = "IIIIII";            channelNames[9] = "JJJJJJ";            int channelNumber = 0;            string line;            Console.Write("Please enter a channel number: ");            line = Console.ReadLine();            if ((int.TryParse(line, out channelNumber)) && (channelNumber > 0 && channelNumber < 10))            {                Console.WriteLine("Channel Name is " + channelNames[channelNumber - 1]);            }            else            {                //The number that was has been entered was wrong.                Console.WriteLine("ERROR: There was an error with the channel name");            }            Console.ReadLine(); //Only here to make sure that the program does not close when you are trying to read the console.        }
