    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>
    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";
    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. In the software world, a lot can change in a very short time, and doing things this way makes it more likely that you will find the best information. You may link to the original discussion in the new thread if you think it may be helpful.
    Good luck.
