guys
My code functioned correctly in all other numbers I input, except when I input 4.2. It should just used up 18 coins, which is 16 quarters and 2 dimes, but instead it used:
25(quarter): 16
10 (dime): 1
5 (nickel): 1
1 (penny): 4
using 22 coins
I did alter the input from float to integer, but it decreased 1 itself automatically when transferring into an integer. What am I missing?
BTW I altered my code a bit to see how it allocate the money into different type of coins. My code:
#include <stdio.h>
#include <cs50.h>
int main(void)
{
printf("Enter how much you are owed:");
float change = get_float();
while(change < 0)
{
printf("Try again:");
change = get_float();
}
printf("This is the change orginally: %f\n", change);
int changes;
changes = change*100;
printf("This is the changes in float: %d\n", changes);
int num_25 = 0;
int num_10 = 0;
int num_5 = 0;
int num_1 = 0;
while(changes >= 25)
{
do
{
changes = changes - 25;
num_25 = num_25 + 1;
}
while(changes >= 25);
}
while(changes >= 10)
{
do
{
changes = changes - 10;
num_10 = num_10 + 1;
}
while(changes >= 10);
}
while(changes >= 5)
{
do
{
changes = changes - 5;
num_5 = num_5 + 1;
}
while(changes >= 5);
}
while(changes >= 1)
{
do
{
changes = changes - 1;
num_1 = num_1 + 1;
}
while(changes >= 1);
}
int num = num_25 + num_10 + num_5 + num_1;
printf("25 cent: %i\n", num_25);
printf("10 cent: %i\n", num_10);
printf("5 cent: %i\n", num_5);
printf("1 cent: %i\n", num_1);
printf("Get %i coins", num);
}
and this is the output when entering change =4.2
