Write a program that prompts the user to specify: The amount of premixed concrete (in cubic yards) ordered The thickness of the patio (in inches) The ratio of length and width Ex. If the ratio is 3 to 2, have the program accept a 3 then a 2. Then compute the ratio using these numbers The program then outputs: The length and width of the patio (in feet). (1 cubic yard = 27 cubic feet.)
Operations
In mathematics and computer science, an operation is an event that is carried out to satisfy a given task. Basic operations of a computer system are input, processing, output, storage, and control.
Basic Operators
An operator is a symbol that indicates an operation to be performed. We are familiar with operators in mathematics; operators used in computer programming are—in many ways—similar to mathematical operators.
Division Operator
We all learnt about division—and the division operator—in school. You probably know of both these symbols as representing division:
Modulus Operator
Modulus can be represented either as (mod or modulo) in computing operation. Modulus comes under arithmetic operations. Any number or variable which produces absolute value is modulus functionality. Magnitude of any function is totally changed by modulo operator as it changes even negative value to positive.
Operators
In the realm of programming, operators refer to the symbols that perform some function. They are tasked with instructing the compiler on the type of action that needs to be performed on the values passed as operands. Operators can be used in mathematical formulas and equations. In programming languages like Python, C, and Java, a variety of operators are defined.

Instructions
A contractor orders, say, 30 cubic yards of premixed concrete to construct a patio that is to be, say, four inches thick. The length of the patio is to be, say, twice the width.
Write a program that prompts the user to specify:
- The amount of premixed concrete (in cubic yards) ordered
- The thickness of the patio (in inches)
- The ratio of length and width
- Ex. If the ratio is 3 to 2, have the program accept a 3 then a 2. Then compute the ratio using these numbers
The program then outputs:
- The length and width of the patio (in feet). (1 cubic yard = 27 cubic feet.)
To calculate the width, you will need to:
- Find the total cubic feet of the concrete
- Divide the total cubic feet of concrete by the result of the length to width ratio multiplied by the thickness of the patio, over 12 (inches in a foot)
- Square root the answer
To find the square root of a decimal number, include the header file cmath using the statement #include <cmath>, in your program.
The function sqrt, included in this header file, determines the square root of a decimal number. For example, sqrt(16.0) = 4.0.
