to communicate the steps needed to write a program

For what purpose does a programmer use flowcharts and pseudocode?

-Flowcharts help us see how the program works and what results are intended. -Knowing the complete process flow from the start helps the programmer create a computer program that will solve the problem. -Flowcharts provide an idea of what data is needed at each point in the program.

Identify the purpose of flowcharts. Check all that apply. (Part 1)

A flowchart, because it is a graphical representation of the steps required to solve the problem.
