What is "static_cast<int>"?

It's a way of type casting, that is, converting data from one of C++'s number types to another. In this case you want to convert from a float to an int.

In C you would write,

change = (int) (t*100)

but I think in C++ the use of static_cast<> is safer.

Problem is at
pennies = (int)(amount / 0.01);

if you want in INT you will always have answer in 0; so you cant calculate pennies.

so you have to change it to..

pennies = (amount / 0.01);

now another thing to do is.. make it round ....

int roundingp = pennies+0.5;

and then
pennies = roundingp;

if i paste your program after making some change here it will be !

# include <iostream.h>
#include<conio.h>

float amount;
float quarters;
float dimes;
float nickels;
float pennies;


int main()
{
cout << "Enter an amount less than $1.00: ";
cin >> amount;

//if (amount == 0)


quarters = (int)(amount / 0.25);
amount -= (quarters * 0.25);

dimes = (int)(amount / 0.10);
amount -= (dimes * 0.10);

nickels = (int)(amount / 0.05);
amount -= (nickels * 0.05);


pennies = (amount / 0.01);
//cout<< pennies;

cout << "You have " << quarters << " quarters" << ".\n";
cout << "You have " << dimes << " dimes" << ".\n";
cout << "You have " << nickels << " nickels" << ".\n";
int roundingp = pennies+0.5;
pennies = roundingp;
cout << "You have " << pennies << " pennies" << ".\n";


getch();
return 0;

}

Result Snapshopt
where input is 0.11

Enter an amount less then $1.00: 0.11
You have 0 quaters.
You have 1 dimes.
You have 0 quaters.
You have 1 pennies.

Welcome to the forums. This thread is reeealllly old, hasn't seen any action in nearly six years, so better left to sleep. As you're a newcomer you might like to read the Code of Conduct, if you haven't already. Here is an excerpt:

If a post is older than a year or so and hasn't had a new reply in that time, instead of replying to it, create a new thread.
