1. Use if - else - elif Write a program to get an integer input from the user. If the input is 25, get the length and breadth from the user and calculate the area of rectangle. [ Area of rectangle = length * breadth] If the input is 40, get the side from the user and calculate the area of square. [ Area of square = side * side] If the input is 65, get the radius from the user and calculate the area of circle. [ Area of circle = 3.14*r"r] Otherwise Display ' Enter number 25 or 40 or 65 .
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.
![1. Use if - else - elif
Write a program to get an integer input from the user.
If the input is 25, get the length and breadth from the user and calculate the area of rectangle. [ Area of rectangle = length * breadth ]
If the input is 40, get the side from the user and calculate the area of square. [ Area of square = side * side]
If the input is 65, get the radius from the user and calculate the area of circle. [ Area of circle = 3.14"r*r]
Otherwise Display Enter number 25 or 40 or 65.
