Algorithm Program
A series of instructions designed to solve a specific problem or accomplish a specific task. A set of instructions written in a programming language that a computer can execute to perform a specific task.
An abstract concept that can be expressed in many ways, such as pseudocode or flowcharts. A concrete implementation of an algorithm that can be executed by a computer.
Can be implemented in any programming language or even in natural language. Must be written in a specific programming language that the computer can understand.
Generally, not optimized for efficiency or speed. Must be optimized for efficiency and speed to run efficiently on a computer.
Can be used as a blueprint for building a program. Is the final product of the software development process.
Does not require a computer to exist, and can be solved by hand. Requires a computer to be executed.

Algorithm for adding two numbers:

  1. Start
  2. Input the first number (num1)
  3. Input the second number (num2)
  4. Add num1 and num2 and store the result in a variable called sum.
  5. Output the sum.
  6. Stop

# Python program to add two numbers

# Take input from the user
num1 = float(input("Enter the first number: "))
num2 = float(input("Enter the second number: "))

# Add the two numbers
sum = num1 + num2

# Display the sum
print("The sum of", num1, "and", num2, "is", sum)
