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 upon inorder 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 :

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

Here, we can see how the steps of a linear search program are explained in a simple, English language.

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 which 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

Let’s see the difference between algorithm and flow chart:-
