Returning counters to 0 ?

Hi,
My change counting program runs perfectly except the counters don't return to 0 when I try another number. The change adds up from the first try. Is there any way to fix this?
#include <stdio.h>

int main()
{
    int toonie=0, dollar=0, quarter=0, dime=0, nickel=0, cent=0;  
    float amount, change, cchange;
    char ch='Y', N, Y;
    
    while(ch=='Y'){
         
    printf("\n Your total is $", amount);
    scanf(" %f", &amount);
    
    change=(5.00-amount);
    printf("\n Your change is $%3.2f\n", change);
    while(change>=0 && change<5.00){
    cchange=(change*100);
    while (cchange>=200){
        cchange-=200;
        toonie++;
        }
    while (cchange>=100){
        cchange-=100;
        dollar++;
        }
    while (cchange>=25){
        cchange-=25;
        quarter++;
        }
    while (cchange>=10){
        cchange-=10;
        dime++;
        }
    while (cchange>=5){
        cchange-=5;
        nickel++;
        }
    while(cchange>=1){
        cchange-=1;           
        cent++;
        }
        
       // print results
       printf(" You have %d coins of 2 dollars \n", toonie);
       printf(" You have %d coins of 1 dollar \n", dollar);
       printf(" You have %d coins of 25 cents \n", quarter);
       printf(" You have %d coins of 10 cents \n", dime);
       printf(" You have %d coins of 5 cents \n", nickel);
       printf(" You have %d coins of 1 cent \n", cent);
       break;
       } // end while
       
       printf("\n Do you want to try again? (Y/N)\n\n");
       ch=toupper(getche());
       
       } // end while
       getch();
       
       }
thanks for your help!

Why not put the initializations in the loop?
"One of the methods used by statists to destroy capitalism consists in establishing controls that tie a given industry hand and foot, making it unable to solve its problems, then declaring that freedom has failed and stronger controls are necessary." --Ayn Rand

An unwritten rule in programming, if your not sure try it anyway and at worst case it wont work it will only unleash mutually assured destruction on us.
And she said "Let there be light" and on the seveth day Windows booted.
And the crowds screamed in terror and cowered in fear for Microsoft had approached.
