For Loop, Array Question

[Marth]

What exactly is going on with this for loop?

is this determining the amount of indices in the array?

and is it putting zero (0) into each index?

  // lets say SYMBOLS == 20
   for (int z = 0; z < SYMBOLS; z++)
		symbolcount[z] = 0;

No, that value appears to be stored in SYMBOLS.

Yes.

It doesn't determine the amount, it resets them all to 0.

// lets say SYMBOLS == 20

for (int z = 0; z < SYMBOLS; z++) means z starts at 0
if z < symbols (20) means as long as z less than SYMBOLS (20)
z++ mean then add 1 to z
So it counts from 0 to 20 using z as the counter variable.
{ starts a block of code
symbolcount[z] = 0; as the value of z increases from 0 to 19, this changes the value of the variable symbolcount[] to 0;
} ends the code block

It is the same as

symbolcount[0] =0;
symbolcount[1] =0;
symbolcount[2] =0;
symbolcount[3] =0;
symbolcount[4] =0;

and so on..

thanks for the help!
