Convert to dollars in C++ How to Tutorial

Convert to dollars
C++

Given four values representing counts of quarters, dimes, nickels and pennies, output the total amount as dollars and cents.

Output each floating-point value with two digits after the decimal point, which can be achieved by executing cout fixed setprecision (2); once before all other cout statements.

Ex: If the input is:

4 3 2 1

where 4 is the number of quarters, 3 is the number of dimes, 2 is the number of nickels, and 1 is the number of pennies, the output is:

Amount: $1.41

For simplicity, assume input is non-negative.

Note: Use named constants (also known as constant variables) for the value of quarters (25) dimes (10) and nickels (5) in cents.

Hello when i tried before to make it by division
Like float dollars = (qtr / 4) + ………
And i defined qtr, dimes, nickels and pennies as int
The result was zero
But when i defined qtr, dimes ….. as float it worked
So why i can’t use a variables int for equations contain division to store the result on variable float ?
