This program will combine the functionality of the previous $2$ programs. It will:

Ask the user if he or she wants to convert from feet and inches to meters or from meters to feet and inches.

The user responds by entering $1$ to convert from feet and inches or $2$ to convert from meters.

Your program will read the users selection and then execute an if else statement to where each branch will contain a call to an appropriate function which will then drive the rest of the application based on that selection.

You must use the following definition of main. The only modification to main should be the addition of the code to insure the user enters either $1$ or $2$ for the choice of conversion. You will build the rest of your program using the functions that you created in problems $2$ and $3.$

int main$()$

$\{$

char ans; $//$loop control variable

int which; $//$stores the choice of conversion

do

$\{$

$//$Add a loop here to insure that the user enters either $1$ or $2$

cout $<<"$

Enter $1$ for English to Metric or $"<<$ endl

$<<$ "Enter $2$ for Metric to English conversion"

$<<$ endl;

cin $>>$ which;

if $(1==$ which$)$

ConvertToMetric$()$;$//$calls the ConvertToMetric functions

else

ConvertToEnglish$()$;$//$calss the ConvertToEnglish functions

cout $<<"$Y or y allows another choice of conversion. $"$

$<<$ "any other quits" $<<$ endl;

cin $>>$ ans;

$\}$ while $(\text{'}$y$\text{'}==$ ans $||\text{'}$Y$\text{'}==$ ans$)$;

return $0$;

$\}$
