Part $4$:

The following sketch solves the following equation and prints the result on the serial monitor.

$k=\frac{x^2+xy-11}{100}$

$x=8,y=2$

int $x=8,y=2,$ temp;

double $k=0\mathrm{.}0$;

void setup$()($

I$/$ put your setup code here, to run once:

Serial begin $(9600)$;

$k=\frac{x**x+x**y-11}{100}$; $//$ line $6$

Serial.print$("$k$=")$;

Serial.println$($k$)$;

$k=\frac{x**x+x**y-11}{100\mathrm{.}0}$; $//$ line $10$

Serial.print$("$k$=")$;

Serial.println$($k$)$;

temp$=$k; $//$ line $14$ Coms $($Arduino$/$Genuino Uno$)$

temp $=k$; $//$ line $14$

Serial.print$("$temp$=")$;

Serial.println$($temp$)$;

Explain why the result in Line $6$ is different than the result in Line $10.$ Also, why is the variable "temp" $($Line $14)$ equal to zero even though $k$ is not?

Write a program that converts a temperature value in Fahrenheit degrees to Celsius degrees and prints it on the serial monitor. $($Use the formula $C=(\frac{5}{9})(F-32)$ for conversion. The temperature in Fahrenheit is defined and initialized as a global variable$).$ Your Serial monitor should be look like Figura$\_8$
