When do we initialize the value of a float to be negative or positive? I recently saw
"float userInput = -1.0;"
but what about
"float userInput = 1.0;"
Are there differences between the two, and when would one be used over the other?
A more detailed example below (a program that calculates the minimum number of coins required to give a user change):
#include <stdio.h>
#include <cs50.h>
#include <math.h>
int main(void)
{
float input = -1;
int z = 0;
int counter = 0;
do
{
printf("The amount of changed owed(in dollars) is ");
input = get_float();
}
while (input < 0);
input = input * 100;
input = round(input);
z = input;
while (z >= 25)
{
z = z - 25;
counter++;
}
while (z >= 10)
{
z = z - 10;
counter++;
}
while (z >= 5)
{
z = z - 5;
counter++;
}
while (z >= 1)
{
z = z-1;
counter++;
}
printf("The number of minimum coins needed is %dn", counter);
}

No, wait. Since now the code actually does something useful, it is on-topic here.

The only missing thing is the#includelines at the top of the file. These are part of "the complete code". According to this site's guidelines, the question title should describe what your code is supposed to do, therefore "Calculating the number of coins in money change" is preferred.
