A flowchart is a type of diagram that represents an algorithm, workflow or process. The flowchart shows the steps as boxes of various kinds, and their order by connecting the boxes with arrows. This diagrammatic representation illustrates a solution model to a given problem.while algorithm a process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer.

5a)

An algorithm is a step-by-step analysis of the process, while a flowchart explains the steps of a program in a graphical way.
