$4.$ Bug Hunt Challenge: Common Mistakes in Control Flow and Loops

Task

Troubleshoot and fix common mistakes related to control flow $($if$-$else$),$ loops, and formatted output.

Instructions

$1.$ Analyze the provided buggy script buggy$\_$script$3.$m:

$\%$ Check if a number is positive, negative, or zero

num $=$ input$(\text{'}$Enter a number: $\text{'})$;

if num $>0$

disp$(\text{'}$The number is positive.$\text{'})$

elseif num $<0$

disp$(\text{'}$The number is negative.$\text{'})$

else

disp$(\text{'}$The number is zero.$\text{'})$

$\%$ Calculate the sum of even numbers between $1$ and $100$ using a while loop

$2$

$\%$ and incrementing i by $2$ for each loop iteration.

sum$\_$even $=0$;

i $=2$;

while i $<=100$

sum$\_$even $=$ sum$\_$even $+$ i;

end

fprintf$(\text{'}$The sum of even numbers between $1$ and $100$ is: $\%$d

$\text{'},$ sum$\_$even$)$;
