C++ Vending Machine program HELP!

OK, so I created my program. It works up until the stage where I enter item number.
Once item number is entered, nothing happens, but it should read out what I have bought and should ask me to enter correct amount and give correct change.
Below is my code.

#include <iostream>
#include <iomanip>                                             
using namespace std;


int main()                                                      
{
char money;
double totalm = 0;
double value = 0, valued = 0, valuen = 0, valueq = 0, valueb = 0;
int c1=1, c2=2, c3=3, c4=4, c5=5, c6=6; // item numbers
int C1=1, C2=2, C3=3, C4=4, C5=5, C6=6;
int item;

	cout<<"======Vending Machine======"<<endl; 
	cout<<"    Enter p to purchase a product    "<<endl; // asks for user input
	cin>>money;

	while(money!='p' && money!='P')

	cout<<"=========Vending Machine========="<<endl; // displays 'vending machine'
	cout<<"    Snickers     Mars     Haribo        "<<endl;
	cout<<"     0.60       0.50     1.50         "<<endl;
	cout<<"       C1          C2        C3          "<<endl<<endl;
	cout<<"     Twirl       Twix      Lion         "<<endl;
	cout<<"     0.50       0.70     0.75         "<<endl;
	cout<<"       C4          C5        C6          "<<endl;
	cout<<"========================================="<<endl;
	cout<<"Please enter item number"<<endl; // asks user to enter item number that they wish to purchase
	cin>>item;

	if (item==c1||C1)
	{
		double S=0.60;
		float change=0;
		if(totalm>=S)
		{
			cout<<"Snickers is purchased"<<endl;
			change=totalm-S;
			cout<<"Money deposited is"<<totalm<<"Your change is"<<change<<endl;
			cout<<"Thank You"<<endl;
		}
		else
		{
		}

		if (item==c2||C2)
	{
		float M=0.50;
		float change=0;
		if(totalm>=M)
		{
			cout<<"Mars is purchased"<<endl;
			change=totalm-M;
			cout<<"Money deposited is"<<totalm<<"Your change is"<<change<<endl;
			cout<<"Thank You"<<endl;
		}
		else
		{
		}

			if (item==c3||C3)
	{
		float H=1.50;
		float change=0;
		if(totalm>=H)
		{
			cout<<"Haribo is purchased"<<endl;
			change=totalm-H;
			cout<<"Money deposited is"<<totalm<<"Your change is"<<change<<endl;
			cout<<"Thank You"<<endl;
		}
		else
		{
		}

			if (item==c4||C4)
	{
		float Tw=0.50;
		float change=0;
		if(totalm>=Tw)
		{
			cout<<"Twirl is purchased"<<endl;
			change=totalm-Tw;
			cout<<"Money deposited is"<<totalm<<"Your change is"<<change<<endl;
			cout<<"Thank You"<<endl;
		}
		else
		{
		}

			if (item==c5||C5)
	{
		float T=0.70;
		float change=0;
		if(totalm>=T)
		{
			cout<<"Twix is purchased"<<endl;
			change=totalm-T;
			cout<<"Money deposited is"<<totalm<<"Your change is"<<change<<endl;
			cout<<"Thank You"<<endl;
		}
		else
		{
		}

			if (item==c6||C6)
	{
		float L=0.75;
		float change=0;
		if(totalm>=L)
		{
			cout<<"Lion is purchased"<<endl;
			change=totalm-L;
			cout<<"Money deposited is"<<totalm<<"Your change is"<<change<<endl;
			cout<<"Thank You"<<endl;
		}
		else
		{
		}
			}
			}

		return 0; // terminates successfully 
			}
			}
		}
	}

}
