Difference Between Algorithm and Flowchart
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.
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:
|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.|
