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.
Question
Transcribed Image Text:2.36 LAB*: Program: Painting a wall
Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
printf("%0.21f", yourValue);
(1) Prompt the user to input a wall's height and width. Calculate and output the wall's area. (2 pts)
Note: This zyLab outputs a newline after each user-input prompt. For convenience in the examples below, the user's input value is shown on
the next line, but such values don't actually appear as output when the program runs.
Enter wall height (feet):
12.0
Enter wall width (feet):
15.0
Wall area: 180.00 square feet
(2) Extend to also calculate and output the amount of paint in gallons needed to paint the wall. Assume a gallon of paint covers 350 square
feet. Store this value using a const double variable. (2 pts)
Enter wall height (feet):
12.0
Enter wall width (feet):
15.0
Wall area: 180.00 square feet
Paint needed: 0.51 gallons
(3) Extend to also calculate and output the number of 1 gallon cans needed to paint the wall. Hint: Use a math function to round up to the
nearest gallon. (2 pts)
Enter wall height (feet):
12.0
Enter wall width (feet):
15.0
Wall area: 180.00 square feet.
Paint needed: 0.51 gallons
Cans needed: 1 can (s)
