Answer in scilab calculate the GPA for a studentWrite a user$-$defined function that calculates grade point average $($GPA$)$ on

a scale of $0$ to $5,$ where $A=5,B=4,C=3,D=2,$ and $F=0.$ For the

function name and arguments, use GPA $=$ GradePtAve $(G,C).$ The input

argument $G$ is a vector whose elements are letter grades $A,B,C,D,$ or $F$

entered as a string $($e$.$g$.,[\text{'}$ABACFB$\text{'}]).$ The input argument $C$ is a vector

with the corresponding credit hours. The output argument GPA is the calcu$-$

lated GPA rounded to the nearest tenth $($i$.$e$.,3\mathrm{.}75$ is rounded to $3\mathrm{.}8,$ and

$3\mathrm{.}749$ is rounded to $3\mathrm{.}7).$ Use the function to calculate the GPA for a student
