Question

anyone can generate the algorithom in plain english?and give an idea the meaning of every shape and value. Its done by flogaritm . Thanks

CALCULATIONS fa Circle Main Real area Integer radius Output Please enter the radius of a circle Input radius area 3 14 radius 2 Output The area is & area End flowgorithm labs 1pdf

Answer 1

// I HAVE PROVIDED EXPLAINATION FOR SHAPES AND THEIR MEANING

// I HAVE GIVEN AN ENGLISH ALGORITHM

// I HAVE ALSO WRITTEN A SAMPLE C CODE FOR FLOWGRAPH AND SHOWN ITS OUTPUT

SHAPES AND THEIR MEANING:-

1- Main
A rectangle with rounded cap ends is used to start and end each flowchart process path.
The shape in which "main" is written is a "rectangle with rounded cap ends".
The above shape is used to mark the start and end of a flowchart.
The symbol here marks the beginning of a program.
The entry point of any program is generally "main" function.
Hence "main" here marks the entry of the program.

2- Real area
The shape in which "Real area" is written is used to denote "declare".
A Declare Statement is used to create variables and arrays.
eg:- float area, here we are declaring a variable called "area" of "float" data type.
whenever we have to declare any variable we use the given shape.
we write the data type of variable and the name of variable inside the shape.

3- Integer radius
The shape in which "Integer area" is written is used to denote "declare".
A Declare Statement is used to create variables and arrays.
eg: int radius, here we are declaring a variable called "radius" of "int" data type.
whenever we have to declare any variable we use the given shape.
we write the data type of variable and the name of variable inside the shape.

4- Output "Please enter radius of a circle"
The shape in which "Please enter radius of a circle" is written is used to denote "output".
An Output Statement evaluates an expression and then displays the result on the screen.
An Output is something which is displayed on screen and shown to the user
Here we are showing user a message to enter radius of a circle.
We are notifying user by displaying the message on the screen.

5- Input radius
The shape in which "Input radius" is written is used to denote "output" as well as "input"
Here we are using to denote "input"
Here it signifies that we want the user to provide the input value for radius

6- area = 3.14 * radius ^ 2
The shape in which "area = 3.14 * radius ^ 2" is written is used to denote "assignment"
The Assignment shape is used to store the result of a calculation into a variable.
Here we are performing some calculation and then storing it in a variable
The "rectangle" shape is used to denote "assignment"
Here we are performing calculation "3.14 * radius ^2"
And then storing that calculation into "area" variable (also called assignment).

7- Output- The area is & area
The shape in which " The area is & area" is written is used to denote "output".
An Output Statement evaluates an expression and then displays the result on the screen.
An Output is something which is displayed on screen and shown to the user
Here we are showing the user the area of circle calculated.
The area of the circle shown is calculated based on the radius the user entered.
We are displaying the result of are calculation based on radius provided to user.
We are displaying results to user in output.

8- End
A rectangle with rounded cap ends is used to start and end each flowchart process path.
The shape in which "end" is written is a "rectangle with rounded cap ends".
The above shape is used to mark the "start and end" of a flowchart.
The symbol here marks the "end" of a program.
It signifies that all the task of the program are done
It signifies the termination of a process or program.

ALGORITHM:-
1- start the program
2- Declare a variable called "area" of real data type
3- Declare a variable called "radius" of integer data type.
4- Output to user "Please enter radius of circle"
5- take radius input from user and store it in variable "radius"
6- compute (3.14 * radius ^ 2) and store it in variable declared "area".
7- Output to user "The area is " and the value stored in "area" variable after it.
8- End the program.

// HERE I HAVE PROVIDED A SAMPLE C CODE

#include<stdio.h>

#include<math.h>

void main()

{

float area;

int radius;

printf("Please enter the radius of a circle ");

scanf("%d",&radius);

area = 3.14 * pow (radius,2);

printf("The area is %f",area);

}
