Consider the following $\text{ANSI C}$ program: #include <stdio.h> #include <stdlib.h> struct Node{ int value; struct Node *next;}; int main( ) { struct Node *boxE, *head, *boxN; int index=0; boxE=head= (struct Node *) malloc(sizeof(struct Node)) ... $\textsf{return}$ which will be reported as an error by the compiler It dereferences an uninitialized pointer that may result in a run-time error

Consider the following $\text{ANSI C}$ function: int SimpleFunction(int Y[], int n, int x) { int total = Y[0], loopIndex; for (loopIndex=1; loopIndex<=n-1; loopIndex++) total=x*total +Y[loopIndex]; return total; } Let $\textsf{Z}$ be an array of $10$ elements with $\textsf{Z}[i]=1$, for all $i$ such that $0 \leq i \leq 9$. The value returned by $\textsf{SimpleFunction(Z},10,2)$ is __________

Consider the following pseudo-code fragment, where $a$ and $b$ are integer variables that have been initialized: /* Pre-conditions : $(a > 1 \wedge a < b)$ */ /* Assume that overflow never occurs */ int $x=0$; int $p=1$; while $(p<b) \{$ $p=p*a$; $x=x+1$; $\}$ ... $\lfloor \: \: \rfloor$ means floor */ $\lfloor \log_a^b \rfloor$ /* $\lceil \: \: \rceil$ means ceil */

Suppose you are compiling on a machine with $1$-byte chars, $2$-byte shorts, $4$-byte ints, and $8$-byte doubles, and with alignment rules that require the address of every primitive data element to be an integer multiple of the element's size. Suppose further that the compiler is not ... ; double r; int i; } A[10]; /*10 element array of structs */ $150$ bytes $320$ bytes $240$ bytes $200$ bytes
