When i submit the finance task, i take an error says: /check route confirms whether username is available. Can you guys help me please?

Hi Marek,

Im very new to this, can u explain from line 30 to 36. From my understanding, (cc_number % 10 = digit1) is to obtain the last number(if im not mistaken)? But why is digit2 = digit1? and why sum_of_even +=digit1? I look forward for your reply and would greatly appreciate a detailed explanation. Thanks!

Hey Marek,

Thanks for your sharing,
I am wandering in pset1 credit line 47, why the code is:
int multiple = 2 * digit1;
sum_of_double_odds += (multiple / 10) + (multiple % 10);
instead of:
(sum_of_double_odds += digit1 * 2) ?
Please correct me if I am wrong, say if the digit is 7, with your code the sum_of_double_odds
would add on 14 / 10 = 1.4 = 1, plus 14 % 10 = 4, which the result would be 5 instead of 14.

I finished my codes for the "Cash" in the problem set 1. It ran well except when I tried 0.42 or other values less than 0.2.

I would be very appreciated if anyone can help me with this problem? The code is provided below.

Thank you a lot.

`#include <cs50.h>
#include <stdio.h>
#include <math.h>

int main(void)
{
int amount;
int pennies;
int dime;
int nickle;
int quarter;

do
{
    float received_money = get_float("Money received: ");
    amount = received_money * 100;
}    
    while (amount <= 0);
    do    
    {
        quarter = amount/25;           
    }
    while (quarter > 25);
                
        do
        {
            dime = (amount%25)/10;                
        }
        while (dime > 10);
            
            do
            {
                nickle =  ((amount%25)%10)/5;                    
            }
            while (nickle > 5);
    
                do
                {
                    pennies = (((amount%25)%10)%5);                        
                }
                while (pennies > 1);                                        
printf ("Cashout: %i\n", pennies + dime + nickle + quarter);
