Programming in C# question

After creating this code:

Console.WriteLine("Hello, and Welcome to Shell Bomber!\n");

Console.WriteLine("In this game you will calculate the distance\n");

Console.WriteLine("a shell will rise and travel along the ground ^_^\n");

Console.WriteLine("theta = ?");           // initial angle that you will ask for from the user

double theta = Double.Parse(Console.ReadLine());

Console.WriteLine("v_o = ?");          // initial velocity that you will ask for from the user

double v_o = Double.Parse(Console.ReadLine());

Console.WriteLine("Calculate v_ox");       //Calculate vox = v_ocos(theta

double v_ox = v_o * Math.Cos(theta);      //Use the Math.Cos(theta) method

theta = theta * Math.PI / 180.0;    // Converts from degrees to radians

Console.ReadLine();

Is the program automatically going to convert the value of double v_ox = v_o * Math.Cos(theta) to a value from the user's input of an angle for theta and an initial value? Because when I run it, the program is not calculating the value? Did I do something wrong or is that just how I made it work?

If you mean the program isn't showing you the value, it is because you never WriteLine() the result.

You need to convert theta into radians before you calculate v_ox.

Once you've done that, just write the value to the console:

Console.WriteLine("Calculate v_ox");       //Calculate vox = v_ocos(theta 

theta = theta * Math.PI / 180.0;    // Converts from degrees to radians 
double v_ox = v_o * Math.Cos(theta);      //Use the Math.Cos(theta) method 

Console.WriteLine("v_ox == {0}", v_ox); // Show this, if you want to see the value

Console.ReadLine();

Are you just missing the line where you output the result to the console? Maybe something like this:

Console.WriteLine("The calculated value is: {0}", theta);
