What is an Algorithm:  An algorithm is a step-by-step procedure or set of rules to solve a specific problem.     OR

                                            Step by StepTextual representation of your Problem solution is known as An Algorithm

Characteristics of a Good Algorithm

  1. Well-Defined Inputs & Outputs – Takes input and produces a clear output.
  2. Definiteness – Each step must be clear and unambiguous.
  3. Finiteness – Must complete in a finite number of steps.
  4. Effectiveness – Each step must be simple enough to be executed.
  5. Independence – Should be language-independent, meaning it can be implemented in any programming language

Here algorithms and Flow chart to Add two numbers entered by the user.

Example:     Algorithm for Exchanging Values of Two Variables

Step 1: Start                                                                                                                                                                                                                              Flow chart  with Two Value
Step 2: Input two variables, say A and B
Step 3: Store the value of A in a temporary variable T
Step 4: Assign the value of B to A
Step 5: Assign the value of T (old value of A) to B
Step 6: Print the new values of A and B
Step 7: End
