Pre$-$lab Flowchart

Before your lab class, draw a flowchart for your proposed program $($see program

specification below$).$ See the Lecture notes for information on how to draw a flowchart.

Remember, a flowchart does NOT contain code. Rather, it is a visual description of an

algorithm and is written in plain English. You may produce your flowchart on a

computer, or$,$ you may NEATLY draw your flowchart by hand on a piece of paper.

Your flowchart is due at the START of your lab class $($submission on paper$)$ and is worth

$20\%$ of this lab$$s grade $($see the APSC $177$ Lab Guide$).$

Program Specification

Write a C$++$ program to:

APSC $177$ Lab $22$

$-$ prompt the user to enter, and then read in$,$ an angle of attack $($

$)$ and the

corresponding measured lift coefficient from Table $1($remember units!$)$

$-$ compute the modeled lift coefficient for the entered angle of attack using the

expression

C $=$ A$$sin$(2$

$/$B$)$

where A $=1\mathrm{.}3[$unitless$],$ B $=95$ degrees and

$$ is in degrees$1$

$-$ compute the percent difference between measured and modeled lift

coefficients. Compute this percentage as the absolute difference between

measured and modeled lift coefficients divided by the modeled lift coefficient$\mathrm{.}1$

$-$ output the angle of attack, measured lift coefficient, modeled lift coefficient, and

lift coefficient percent difference as in the following example of user$/$computer

interaction

$-$

Enter the angle of attack in degrees: $24$

Enter the corresponding measured lift coefficient: $1\mathrm{.}281$

Angle of attack in degrees $24$

Measured lift coefficient $1\mathrm{.}281$

Modeled lift coefficient $1\mathrm{.}29982$

Percent difference $1\mathrm{.}44807$

$-$ use a constant for pi $($using the arccosine function$1)$
