WHAT IS THE ALGORITHM? USES OF THE ALGORITHM

I am not going to definition. We perform many tasks everyday in our life. We have to follow some steps to complete our tasks. Here the task work as a problem. Suppose, you want to prepare a cake. You will need to follow some steps to prepare a tasty cake. But if you make some mistakes or don't follow the steps properly while preparing a cake then the cake may be spoiled. The Algorithm works like that. We need to write computer programs to work with computer. We need to follow some steps to write codes for working special works with computer. For that we need to think how computer can perform tasks. In this situation we use computer Algorithm. The Algorithm is a process which helps to solve problems. We can use Algorithms in JavaScript, PHP, C, C++, C#, Python, Java and many more programming languages. Algorithm is mainly a step-by-step problem solving process. We need to write programs continuously. In the last step, we have to print the program in order to get the result.
Uses of the Algorithm
Generally there is a lot uses of Algorithm in a program. If a programmer create an Algorithm before writing program the number of error will be decreased in his program. We need to write Algorithm before creating Flowchart too. Otherwise, there will be a lot of errors. We need to write algorithm before solving mathematical problems too. Suppose you want to create a negative and positive number detector. At first we need declare a variable. Then we need to take a number as input from users and store it. then our program will detect that whether it is positive or negative number. This is a very simple and short algorithm and it's easy for you to learn. We can see the use of Algorithm in AI, space research, robotics etc. As an example, we use YouTube to watch different videos. If we watch and like some food challenge videos then YouTube will suggest us some videos related to food in the main page. That's also an example of an algorithm. Every programs and websites we use is mainly the sum of some algorithms. I hope you have understand algorithm very well.
Some characteristics of the Algorithm
There are some requirement for writing algorithm.
1. Unambiguous. The algorithm must be clear and correct. Every steps must have some meanings.
2. Finiteness. Every algorithm must be finished within some steps. It can also be repeated finitely.
3. Input. It ensures that the data entered by the user is acceptable or not.
4. Output. It is generally the final step of Algorithm. Output helps to get the outcome of our program. We need to get the result in output for which we have created our Algorithm.
5. Effectiveness. If the Algorithm has been written within a short time and space or has taken a short time to execute and runs within a short space, then it's the effectiveness of the Algorithm.
Job opportunities
Well, the job opportunities of Algorithm writer is still low. Nowadays, the demand of an Algorithm writer is increasing. In freelancing sites, there are many demands of an Algorithm writer but it's lower that a web developer or computer programmer. But with the progress of IT the demand is highly growing up.
