What is an algorithm?

An algorithm is a step-by-step procedure of solving a logical or mathematical problem.

What is a flowchart?

A flowchart is a type of diagram that represents an algorithm or the process to solve a problem.

What is the purpose of a decision-making flowchart?

A decision-making flowchart helps in coming to a decision based on some logic.

How does a simple flowchart move?

A simple flowchart moves only in the vertical direction, from top to bottom.

What is the characteristic of decision symbols in a flowchart?

Decision symbols in a flowchart have two exit points: one for Yes/True and another for No/False.

Study Notes

Problem-Solving and Algorithms

  • Problem-solving involves any activity or task undertaken to achieve a specific goal or objective.
  • Examples of problem-solving include packing a school bag according to a timetable, watching a favorite TV channel, going shopping, or going to a movie.

Algorithms

  • An algorithm is a step-by-step procedure for solving a logical or mathematical problem.
  • It involves dividing a problem-solving process into sequential steps.

Flowcharts

  • A flowchart is a diagram that represents an algorithm or problem-solving process.
  • It uses various symbols to represent the flow of a process.
  • Flowcharts can be simple or complex, depending on the problem they represent.

Simple Flowcharts

  • A simple flowchart involves only input, process, and output.
  • It moves only in a vertical direction (top to bottom).

Decision-Making Flowcharts

  • Decision-making flowcharts help make decisions based on logic.
  • They have at least one decision symbol with two exit points (Yes/True and No/False).
  • These flowcharts are used to raise a condition along with its solution.

Loop-Based Flowcharts

  • Loop-based flowcharts involve a process repeated until a certain condition is met or fulfilled.

Learn about problem-solving and algorithms, which are step-by-step procedures used to solve logical or mathematical problems. Explore how activities and tasks are performed to achieve specific goals, like packing a school bag or going shopping.
