Hello:)

Previously I have made a temperature convertor web app with code behind the button click.
I have now been asked to do one using methods/functions and am getting stuck on vaiables to pass and how I do it. Could someone explain variable naming and passing to me in a way that I can finally get it to remain in my thick head please:confused:.
Below is the pseudocode and my attempt - which I know is confused.

Thank you.

Structured English
Function (button click)
BEGIN
CALL Input_function
CALL Calc_function
CALL Display_function
END

Input_function
BEGIN
OBTAIN Init_Temp
OBTAIN Conversion_type
END

Calc_function
BEGIN
IF Conversion_type = FtoC THEN
New_Temp = (Init_temp -32)/1.8
END IF
IF Conversion_type = CtoF THEN
New_Temp = (Init_temp *1.8) + 32
END IF
END

Display_function
BEGIN
DISPLAY New_TEMP
END


And my attempt ...

namespace TemperatureConvertorPractice
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

            private void btnConvert_Click(object sender, EventArgs e)
            {           
                float inputTemp = inputMethod(Temp); //CALL Input_function   
                float returnTemp = calculateTemp(newTemp); //CALL Calc_function
                float newTemp = displayAnswer(answerTemp); // CALL Display-fuction
            
            }
     

            public float inputMethod(float Temp) // this is the method for calculating the conversion OBTAIN initialTemp and OBTAIN Conversion type
            {
                float temp = float.Parse(txtInitialTemp.Text);// get initial temp (converts string representation of number to float)
                return temp;        
            }

            public float calculateTemp(float initialTemp)// (float fTemp, float cTemp)this is the method for calculating the conversion
            {     
                try
                {//open try
                    if (rbtnFtoC.Checked == true) //if you are converting from F to C
                    {
               
                        float newTemp = (initialTemp - 32) * 5 / 9;//Do Calculation- formula for F to C       
                        return newTemp; //Return Result                 
                    }

                    else if (rbtnCtoF.Checked == true)//if you are converting from C to F
                    {
                        float newTemp = (initialTemp * 9 / 5) + 32;//Do Calculation- formula for C to F 
                        return newTemp;//Return Result               
                    }


                }//close try
                catch (Exception w)
                {
                    MessageBox.Show("Please enter a number because " + w.Message);//Mesage Box if letter entered
                    txtNewTemp.Clear();//clears Celsius text box if you enter a letter
                    txtInitialTemp.Clear();//clears Fahrenheit text box if you enter a letter
                }

            }


          public float displayAnswer(float answerTemp)
          {
              txtNewTemp.Text = answerTemp.ToString();
              return answerTemp;
          }

your question doesnt seem clear, do u have any errors, if so, post them.
otherwise the above code should work properly, the parameter passing to methods are proper.
