2015 has been a very active year for volcanoes. It's a very active year for ascii art volcanos too

           \/\/\//<---------------- Peak of Eruption
            \   /
             \_/<------------------ Base of Eruption
             / \<------------------ Peak of volcano
            /   \
           /     \
          /       \
         /_________\<-------------- Base of Volcano

CHALLENGE:

Create a code (via function, stdin, etc) that accepts 2 inputs

Input1 = Distance in lines between base and peak of volcano

Input2 = Distance in lines between base and peak of eruption

Based on these inputs, program should output to the console (stdout) the ASCII depiction of a volcano eruption

SAMPLES:

DrawEruption(Arg1 = VolcanoHeight, Arg2 = EruptionHeight)

INPUT: DrawEruption(9, 4)

OUTPUT:

How to post solution?

Language Name, Size of Program in Bytes - C#, 500 bytes, source code

How to size of program?

Compiled Languages - U can either count the size in bytes from the EP of the binary to the last instruction or the byte size of the ASCII code - whichever is shorter. C# can use byte size of ASCII code (as in .cs file) or the ASCII byte size of compiled ilasm instructions.

Interpreted Languages - Count the size in ASCII bytes of the source. print 'hello world' would be 19 bytes

Golfing Languages - CJam, Brainf$ck, golfscript, APL, Pyth, ><>, etc. will take a 250 byte penalty, so that other languages can have a chance.

These rules are designed so that all languages have an equal chance of winning & no certain language has any advantage.

Who wins?

The shortest code!

Bonus for drawing console animated eruptions or adding other ASCII effects!

 

 

To set some baseline to compete against: C#, 0x103 bytes of IL code (VS2010, compiled in release mode).

        static void DrawEruption(int volcanoHeight, int eruptionHeight)

            string forwardslash = @"/";

            // print eruption
            for (int eruption = 0; eruption < eruptionHeight; eruption++)
            {
                string s = twospace;
                string ss = onespace;
                if (eruption == 0)
                {
                    s = @"/\";
                    ss = forwardslash;
                }
                if (eruption == eruptionHeight-1) ss = "_";

                // print spacing
                for (int i = 0; i < Math.Max(0, volcanoHeight - eruptionHeight) + eruption; i++)
                    Console.Write(onespace);

@simple : I'm not sure I understood correctly how to count "ASCII byte size of compiled ilasm instructions."  Please correct me if I'm wrong - sample exe attached.

I'll change that, after looking at how you sized it's a better way.

Small code u wrote there kao!

end

Messy,I know.

Usage : drawEruption(volcanoHeight,eruptionHeight)  or drawEruption volcanoHeight,EruptionHeight

Small 32bit executable,just to test it,packaged with Ocra.

@Redouane: what am I missing here?
