Difference Between Algorithm and Flowchart

Analysis of AlgorithmsAlgorithmsMisc Algorithms

In this post, let us understand the differences between a flowchart and an algorithm.

Algorithm

  • It is defined as a sequence of well-defined steps.
  • These steps provide a solution/ a way to solve a problem in hand.
  • It is a systematic, and a logical approach, where the procedure is defined step-wise.
  • It gives the solution to a specific problem.
  • This solution would be translated to machine code, which is then executed by the system to give the relevant output.
  • Many simple operations are combined to help form a more complicated operation, which is performed with ease by the computer.
  • Algorithms can be represented using natural language, flowchart and so on.
  • It is difficult to understand.
  • Plain text is used.
  • It is easy to debug.
  • Its construction is tough.
  • There are no rules to follow while constructing it.
  • It can be understood as the pseudocode for a program.

Algorithm for linear search

  • Start searching for an element from the left-most part of the array.
  • Compare one element every iteration with the item_to_be_searched.
  • If no matches are found, return -1.
  • Otherwise, return the index at which the element is present.

Flowchart

  • It is a graphical representation of an algorithm.
  • Programmers use it as a program-planning tool in order to solve a problem.
  • It uses symbols that are inter-connected.
  • This will help indicate the flow of control and information, and processing.
  • The process of drawing a flowchart for an algorithm is known as "flowcharting".
  • It is a diagram that can be created using different shapes to represent flow of data.
  • It is easy to understand.
  • It is difficult to debug.
  • It is easy to build.
  • Certain riles are to be followed while building it.
  • It is a graphical representation of logic.
