Help me! why it doesn't compile?

void graph(const int askeriskCount[], int lastPlantNumber)

printAsterisks(asteriskCount[plantNumber-1]);

Sorry Moschops, I didn't understand the problem by your response.

When I try to compile I get:

error C2065: 'asteriskCount' : undeclared identifier

This means that it's not declared. As Moschops underlined, you've spelled this wrong.
