Flowchart,Algorithm,Pseudo Code in Detail -Problem Solving Techniques

                                     Hello guys !! Today we will see what are best tips for writing Flowchart, Algorithm, Pseudo code.

                       Step by step this page describes what is Flowchart?, What is algorithm?, What is pseudcode?And also take a look at how to draw and write them correctly.We are also going to see Applications of  Flowchart , Algorithm, Pseudo code.

                       The Problem Solving Techniques include Flowchart , Algorithm, Pseudo code, and Program.They are common to all languages may be in C or C++ or java or python,etc.

                      Lets Start.....

Flowchart:-

           It is a diagramatic representation of flow of execution of program .Each step in  the flow chart is represented by the different symbol  and the symbol  contains  short  description of the process.

                The symbols are linked to each other with arrows showing the direction of the flow.the standard symbols are as follows:-

start/stop = ⭘

input/output = ▱

general = ▭

decision = a rhombus symbol

connector =  ⬅

Algorithm:-                        

             

                   It is the logical sequence of operations described in precise sequence.A algorithm is to be prepared before writing the program . It is mainly written in english language.

example:- for addition of 2 numbers

1.     start

2.     read a , b

3.     calculate c= a + b ;

4.     display c

5.     stop

PseudoCode:-

             Some statements will be converted into higher level language it is a informal high level description of the operating principal of a operating program or algorithm.

example:-( for addition of 2 numbers )

     

1.     start

2.     input 2 numbers

3.     calculate sum

4.     output sum

5.     stop

Actual Application :-

Flowchart:-

Algorithm:-

1.       start

2.     declare integer variables r , ar , cir

3.     accept the value of radius of circle from user

4.     ar =  r * r * 3.14;  

5.     cir = 2 * 3.14 * r;

6.     print the area and circumference of the circle.                 

Program :-

The Flowchart and Algorithm will remain same only program code will differ w.r.t. coding language.

If u have chosen C language here is the code... 

#include<stdio.h>                                                                          

#include<conio.h>

void main()

{

  int r = 0 , ar = 0 , cir = 0 ;  

  clrscr();                               

  printf("\n Enter the radius of circle");

  scanf("%d",& r);                 

  ar =  r*r*3.14;                     

  cir = 2*3.14*r;

printf("\n The area of circle is = %d \n The circumference of circle is = %d ", ar , cir);

getch();

}
