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$1)$
