Problem Solving Methodology and Techniques

What is  Algorithm ?

The algorithm is defined as the step-by-step solving of a problem in the user's language.  

It is considered an effective procedure for solving a problem with an infinite number of steps.  The characteristics of the algorithm are,

 Precise

 Unambiguous

 Finite termination

 Unique solution

Once the algorithm is written, it can be coded into a problem using any programming language.  The algorithm uses 3 different constructs

Sequence: sequence says that instructions are to be executed in what order or sequence.

Branching or decision making: Branching involves testing or condition and based on the outcome of the condition testing different instruments are executed.

Repetition: Repetition means one or more instructions shall be repeated several times.  This is otherwise called a loop.  There are different types of loops such as,

 do-while, for




What is  Pseudocode ?

It is a concise description algorithm in the English language that uses programming language constructs.  

The flowchart can be considered as an alternative to pseudo-code.  

Several constructs/keywords of programming language can be used in the algorithm to write the pseudo-code.  Some of them are

 If............Endif

 Do while.......and

 While.......endwhile

 Repeat.........until

 For......endfor

 Case.......endcase

 Call

 Return


What are Programming Language ?

Programming language is a tool to express the logic or instructions for the understanding of the computer.  

Any programming language has two components.

 Syntax

 Semantic

Syntax: syntax refers to the rules to be followed for writing valid program statements.  The compiler can detect an error in syntax while compiling the program.

Semantic: semantic is associated with the logic of the program.  The compiler can not detect the semantic error.  The user of the programmer can diagnose the semantic error.

There is a good number of high-level languages, each meant for a specific area of ​​data processing.  

Commonly known languages ​​are BASIC, FORTRAN, COBOL, Pascal, C, C++, etc.  

While FORTRAN, is good for numerical and scientific calculation, COBOL is good for business applications involving a large amount of data handling.


Generation of Programming Language 

The programming language can be classified into 4 generations.

 1st Generation: Machine Language

 2nd Generation: Assembly Language

 3rd Generation: High Level Languages

4th Generation: Very High-Level Languages


Structured of programming language 

Structured programming language is also known as modular programming.  In this type of programming technique, the program shall be broken into several modules.  

This helps in managing memory efficiently as the required module of the program will be loaded into the memory only and not the entire program.  

This will also enhance code reuse.  Writing, understanding debugging, and modifying the individual module of the program is also easier.


Properties of problem-solving methodology 

This method is completely scientific, in this method the children gain knowledge only scientifically.  And whatever the education system is, it is all done scientifically.

 The problem-solving methodology can easily solve any problem, and students can also learn a lot from it and can develop their skills and skills.

 This method motivates the students to take action.  In this method, there is more contact between student and teacher.  The problem-solving methodology is a technique by which you can easily solve any problem.  The problem-solving methodology can be used to solve the problem, be it programming or any physical.

 Problem Solving Methodology You can do it in all types of programming, it is such a method by which you can solve your problem by taking a few steps very easily.

 It is mostly used in coding, as if there is a big problem in your programming, then there you can use this technique to solve that problem.  As you must be knowing from its name that problem-solving methodology means the method or step which is followed to solve the problem and can solve the big problem easily, it is called problem-solving methodology.

We also need it in our lives and in coding also, if there is some problem with a big complex program in coding then we can use this technique on our own.  And if anything happens in our life, then we solve it, then we can also call it problem-solving methodology.  It simply means that the technique you use to solve a problem and whatever steps you use with it is the problem-solving methodology.

What is Internet how does it Work ?

The Internet today is an amazing technology that knows everything. If the internet was not there, it would not have been as fast as the world is moving today. In today's time, everyone uses the internet and why should everything become so easy with the help of the internet.  But not as much as the Internet is beneficial, but it is also harmful. So if you also use the Internet, then you should know about the Internet.  That is why I have done this article for all of you so that everyone can understand the internet in a very easy and simple language. So let's know with complete information about the internet. What is the internet? The internet is that the largest network within the world, connecting many computers.  A network may be a group of two or more computer systems linked together. The internet is a wire that is in the sea around the world.  And this wire keeps information and data moving around the world. This data can be anything like text, mp3, document, imag...

What is a Data Structure and its Types ?

If you also like to read computer-related information or if you are a computer science student, then this post can be beneficial for you.  In this article, I have explained what is a data structure?  How many types of data are there?  And many more.  To understand the data structure, we need to know what is data.  So let's know about the data and its structure. What is Data ? Data is any row fact or value are called data. Value can be anything if there is any value like 1,2,3,4,5,6 all these have value means it is data.   If we talk about the second example, then a book is also data because it is a book, and the book has value.  Meaning that even the thing which has some value is called data. What is Information ? Information is processing data.  Meaning that if any data is on process mode then we can call that data information.   For example, if we talk about an example, I told you that "you come to me", so the one who told me is ...
