Program not compiling.

[xDJ23x]

I don't understand why this program will not compile. I know the program is kind of long but I would really appreciate any help. I am not very advanced in C++ so I figured some of you guys would be able to pick out the problem. Thanks!

	int skipFactor;
	Tree nuts;
	Squirrel squirrel;
	
	cout<<"Please enter the number of squirrels: "<<endl;
	cin>>numSq;
	for(int i=0;i<=numSq;++i){

	}

	for(int i=0;i<=numTree;++i){

	}

	cin>>skipFactor;
	set_skip_factor(skipfactor);

	while(nuts.nuts_left!=0){
		++count;
		cout<<"Round: "<<count<<endl;
	for(int i=0;i<=numTree;++i){

What is the first error returned by the compiler?

Also, what is this?

int numSq[];
	...
	cout<<"Please enter the number of squirrels: "<<endl;
	cin>>numSq;
	for(int i=0;i<=numSq;++i){
		numSq[i];
	}

numSq is a pointer to an int, and then you write directly into that, changing its value to some location (which you also intend to be the number of squirrels, which is absolutely insane), then you loop based on the value of that pointer and all you do in the loop is nothing?

I think you don't understand what a pointer is, and that's going to cripple you. Please read about pointers: http://www.cplusplus.com/articles/EN3hAqkS/

and second, third, so on and so fo(u)rth.

The program crashes. Doesn't give any errors unless you press cancel while it is compiling. Compiler doesn't finish itself. Its like it gets caught in a loop.

[Moschops]

Read my earlier edit. You've gone horribly wrong in understanding pointers.

[xDJ23x]

That was suppose to put each squirrel into an array. Like squirrel 1, squirrel 2..so on.

[Moschops]

int numSq; // This is just an int.
cout<<"Please enter the number of squirrels: "<<endl;
cin>>numSq;

// Now need to make an array big enough for all the squirrels
int* squirrelArray = new Squirrel[numSq];

// Done. squirrelArray is the array of squirrels  

[xDJ23x]

Thanks, Moschops. Still won't compile. When I press cancel it takes me directly to hoard.h and has an error by #include"squirrels.h"

This will go a lot faster if you read the actual error as well as just looking where the magic arrow points.
