$(20$p$)$ Write the output of the following C program.

#include $$stdio$.$h$$

void foo$($int $x,$ int $***y,$ int $***z,$ int $w)$

$\{x++$;

$**y=**y+1$;

$(**z)+=1$;

w $--$;

$\}$

int main$()$

$\{$

int $A[]=\{0,1,2,3\}$;

foo$(A[0],$&$A[1],A+2,**(A+3)$;

printf$("\%$d$,\%$d$,\%$d$,\%$d$",$ A$[0],$ A$[1],$ A$[2],$ A$[3])$;

$\}$

$(25$p$)$ For a given integer array $A[],$ whose size is $M$ and whose element values

range between $0$ and $N-1,$ the following program computes $C[i](0iN-1),$ the

number of elements in A$[]$ which are less than or equal to i $($for our example A$[],$

the printf statement will print $C[0]=1C[1]=2C[2]=4C[3]=6,$dots,$C[8]=13C[9]=15$; e$.$g$..$

$C[2]=4$ since there are four elements, $A[2],A[3],A[9],$ and $A[11],$ which are $2).$

#include $$stdio$.$h$$

#define M $15$

#define N $10$

int $A[M]=\{3,5,2,1,5,6,9,3,7,0,5,2,4,9,7\}$;

int $C[N]=\{0,0,0,0,0,0,0,0,0,0\}$;
