Lab $4$ Part II: Local and Global Variables

Step $1$: Depending on your operating system, download $($lab$4$

$\_$part$2\_$win.zip or

lab$4$

$\_$part$2$

$\_$macOS.zip$)$ the starting code from Brightspace and extract the zipped file.

Step $2$: Open the unzipped folder in VS Code

Step $3$: lab$4\_$part$2\_$xxx folder contains the following files:

$$ lab$4$test.h contains the declarations $($function prototypes$)$ for the functions defined in

lab$4$test.c Do not modify lab$4$test.h and lab$4$test.c$.$

$$ main.c contains the main function. Do not modify main.c

Step $4$: Open each of the files, get familiar with the variables and identify the scope of each of them.

Step $5$: Answer the following questions and show your answers to the TAs:

$-$ What is the scope of variable$1$ defined inside main.c$?$

$-$ Are any of the variables variable$1$ defined inside lab$4$test.c the same as the variable defined inside

main.c$?$

$-$ Does the assignment statement inside lab$4$test.c $($line $7)$ modify the content of variable$1$ inside

main.c$?$

$-$ How many distinct variables i there are in main.c$?$ If more than one, what is the scope of each of

them?

$-$ How many distinct variables variable$1$ there are in main.c$?$ If more than one, what is the scope

of each of them?

$-$ In lab$4$test.c$,$ is the variable$1$ inside test$2$ the same as the variable inside test$1?$
