The following C program is given $($note that standard C does not allow

nested $($e$.$ nested$)$ functions but this can be translated with the GNU gcc compiler$).$

Assume that main$()$ has its own call entry $($like other functions$).$

a$.$ Show the stack of prompts, with dynamic and

static chains, permanent variables and parameters, as he sees

out when the run reaches the location marked by the arrow in the quickSort$()$ function

$($the previous call to quickSort$()$ in the if$-$loop is running but not done$).$

b$.$ In prompts in programming languages that use dynamic

scope rules must store both the name and value of the variables, but only the value $($not the name$)$ must be stored when static

scope rules are used. Explain this difference.
