int z,x=5,y=-10,a=4,b=2;
z = x++ - --y * b / a;
What number will z in the sample code above contain?
Choice 1 5
Choice 2 6
Choice 3 10
Choice 4 11
Choice 5 12

Q2:
With every use of a memory allocation function, what function should be used to release allocated memory which is no longer needed?
Choice 1 unalloc()
Choice 2 dropmem()
Choice 3 dealloc()
Choice 4 release()
Choice 5 free()

Q3:
void *ptr;
myStruct myArray[10];
ptr = myArray;
Which of the following is the correct way to increment the variable "ptr"?
Choice 1 ptr = ptr + sizeof(myStruct);
Choice 2 ++(int*)ptr;
Choice 3 ptr = ptr + sizeof(myArray);
Choice 4 increment(ptr);
Choice 5 ptr = ptr + sizeof(ptr);

Q4:
char* myFunc (char *ptr)
{
ptr += 3;
return (ptr);
}
int main()
{
char *x, *y;
x = "HELLO";
y = myFunc (x);
printf ("y = %s \n", y);
return 0;
}
What will print when the sample code above is executed?
Choice 1 y = HELLO
Choice 2 y = ELLO

Choice 3 y = LLO
Choice 4 y = LO
Choice 5 x = O

Q5:
struct node *nPtr, *sPtr; /* pointers for a linked list. */
for (nPtr=sPtr; nPtr; nPtr=nPtr->next)
{
free(nPtr);
}
The sample code above releases memory from a linked list. Which of the choices below accurately describes how it will work?
Choice 1 It will work correctly since the for loop covers the entire list.
Choice 2 It may fail since each node "nPtr" is freed before its next address can be accessed.
Choice 3 In the for loop, the assignment "nPtr=nPtr->next" should be changed to "nPtr=nPtr.next".
Choice 4 This is invalid syntax for freeing memory.
Choice 5 The loop will never end.

Q6:
What function will read a specified number of elements from a file?
Choice 1 fileread()
Choice 2 getline()
Choice 3 readfile()
Choice 4 fread()
Choice 5 gets()

Q7:
"My salary was increased by 15%!"
Select the statement which will EXACTLY reproduce the line of text above.
Choice 1 printf("\"My salary was increased by 15/%\!\"\n");
Choice 2 printf("My salary was increased by 15%!\n");
Choice 3 printf("My salary was increased by 15'%'!\n");
Choice 4 printf("\"My salary was increased by 15%%!\"\n");
Choice 5 printf("\"My salary was increased by 15'%'!\"\n");

Q8:
What is a difference between a declaration and a definition of a variable?
Choice 1 Both can occur multiple times, but a declaration must occur first.
Choice 2 There is no difference between them.
Choice 3 A definition occurs once, but a declaration may occur many times.
Choice 4 A declaration occurs once, but a definition may occur many times.
Choice 5 Both can occur multiple times, but a definition must occur first.

Q9:
int testarray[3][2][2] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12};
What value does testarray[2][1][0] in the sample code above contain?
Choice 1 3
Choice 2 5
Choice 3 7
Choice 4 9
Choice 5 11
Q10:
int a=10,b;
b=a++ + ++a;
printf("%d,%d,%d,%d",b,a++,a,++a);
what will be the output when following code is executed
choice 1 12,10,11,13
choice 2 22,10,11,13
choice 3 22,11,11,11
choice 4 12,11,11,11
choice 5 22,13,13,13
