These are also known as peripheral devices and some of the most common examples of input devices are keyboard and mouse. Output devices… any hardware device used to send data from a computer to another device or user. examples of output devices are monitors and projectors (video), headphones and speakers (audio), or printers and plotters (physical reproduction in the form of text or graphics).

What is the magnitude of the largest positive value you can place in a bool? a char? an int? a float?
MaRussiya [10]

Answer:

A bool can hold only true or false values.

A char can hold maximum 65535 characters.

An int can hold maximum positive value of 2,147,483,647.

A float can hold maximum positive value of 3.4 x 10^{38}.

Explanation:

Primitive data types in Java language can be categorized into boolean and numeric data types.

Numeric can be divided further into floating point and integral type. Floating data type includes float and double values while and integral data type which consists of char, int, short, long and byte data types.

Every data type has a range of values it can hold, i.e., every data type has a minimum and maximum predefined value which it is allowed to hold. The intermediate values fall in the range of that particular data type.

Any value outside the range of that particular data type will not compile and an error message will be displayed.

The data types commonly used in programming are boolean, char, int and float.

A boolean variable can have only two values, true or false.

A char variable can hold from 0 to 65535 characters. Maximum, 65535 characters are allowed in a character variable. At the minimum, a char variable will have no characters or it will be a null char variable, having no value.

An int variable has the range from minimum -2^{31} to maximum 2^{31} – 1. Hence, the maximum positive value an int variable can hold is (2^{31}) – 1.

A float variable can hold minimum value of 1.4 x 10^{-45} and maximum positive value of 3.4 x 10^{38}.

The above description relates to the data types and their respective range of values in Java language.

The values for boolean variable remain the same across all programming languages.

The range of values for char, int and float data types are different in other languages.

Problem: Write the Python code of a program called ComputeSquare that asks the user to enter the length of the side of the squar
Lera25 [3.4K]
<h2>Solution :</h2>

The given problem is solved in Python.

def ComputeSquare():

side = float(input('Enter the side of the square: '))

if side > 0:

perimeter = 4 * side

area = side * side

print('Perimeter of the square is:',

perimeter, 'unit.')

print('Area of the square is:', area, 'square unit.')

<h3> else:</h3>

print('Invalid input.')

ComputeSquare()

<h2>Explanation :-</h2>

  • In this program, we create a function ComputeSquare() to calculate the perimeter and area of a square.

  • The function asks the user to enter the side of the square. The side is then stored in a variable.

  • Now, we check whether the side is greater than 0 or not using if-else statement.

  • If the condition is true, the perimeter and area is calculated which is displayed using print() statement.

  • If the condition is false, the else blocks executes printing the error message.
