What is an Algorithm?

The word Algorithm means “a process or set of rules to be followed in calculations or other problem-solving operations”. Therefore Algorithm refers to a set of rules/instructions that step-by-step define how a work is to be executed in order to get the expected results. Let’s take a look at an example for a better understanding. As a programmer, we are all aware of the Linear Search program. (Linear Search


Algorithm of linear search:

  • Start from the leftmost element of arr[] and one by one compare x with each element of arr[]. 
  • If x matches with an element, return the index. 
  • If x doesn’t match with any of elements, return -1. 

What is a Flowchart?

A flowchart is a graphical representation of an algorithm. Programmers often use it as a program-planning tool to solve a problem. It makes use of symbols that are connected among them to indicate the flow of information and processing. The process of drawing a flowchart for an algorithm is known as “flowcharting”. Example: Draw a flowchart to input two numbers from the user and display the largest of two numbers  


Difference between algorithm and flow chart:

S. NoAlgorithmFlowchart
1.An algorithm is a step-by-step procedure to solve a problem.A flowchart is a diagram created with different shapes to show the flow of data.
2.The algorithm is complex to understand.A flowchart is easy to understand.
3.In the algorithm, plain text is used.In the flowchart, symbols/shapes are used.
4.The algorithm is easy to debug.A flowchart is hard to debug.
5.The algorithm is difficult to construct.A flowchart is simple to construct.
6.The algorithm does not follow any rules.The flowchart follows rules to be constructed.
7.The algorithm is the pseudo-code for the program.A flowchart is just a graphical representation of that logic.
