variable value not being set

according to the output expected my program works fine except on the last line where the limit is supposed to be 3. My output shows 0, where am I going wrong???
The output is here http://www.cs.uh.edu/~svenkat/lib/as...ASSIGN1/output

the main.cpp for the .h and its accompanying .cpp is here http://www.cs.uh.edu/~svenkat/lib/as...N1/assign1.cpp .

The .h file

Code:

class ModuloCounter
{
public:
	ModuloCounter(int );
	ModuloCounter(const ModuloCounter& theCounter);
	~ModuloCounter();
	void increment (void);
	void decrement (void);
	static int getNumberofModuloCounters(void);
	int getCounterLimit(int)const;
	int getCounterValue(void)const;

private:
	int modLim;
	int currVal;
	static int modCount;
};

.cpp file

Code:

#include "ModuloCounter.h"

int ModuloCounter::modCount=0;



ModuloCounter::ModuloCounter(int set)
{
	
	modLim=set;
	currVal=1;
	modCount++;

}

ModuloCounter::~ModuloCounter()
{
	modCount--;
}

void ModuloCounter::increment(void)
{
	if(currVal==modLim)currVal=1;
	else currVal++;
}

void ModuloCounter::decrement(void)
{
	if(currVal==1)currVal=modLim;
	else currVal--;
}

int ModuloCounter:: getNumberofModuloCounters(void)
{
	
	return modCount;
}

int ModuloCounter:: getCounterLimit(int limit)const
{
	limit=modLim;
	return limit;
}

int ModuloCounter:: getCounterValue(void)const
{
	return currVal;
}

ModuloCounter::ModuloCounter(const ModuloCounter& theCounter)
{
	currVal=theCounter.currVal;
	modCount++;
	modLim=theCounter.modLim;

}

Code:

int ModuloCounter:: getCounterLimit(int limit)const
{
	limit=modLim;
	return limit;
}

See the problem?

See the problem?

Clearly he doesn't or he wouldn't be asking. The problem is that limit in this context is a copy of the limit that was passed to the function. It needs to be a reference for any changes to take effect.

Code:

int ModuloCounter:: getCounterLimit(int& limit)const
{
	limit=modLim;
	return limit;
}

aah thanks alot guys!!!!
