2. Question 1 : Evaluate each of the following expressions
int x[4] = {12, 20, 39, 43}, *y; y = x;
Assume each expression is evaluated after the previous one (take all previous ones in consideration)
*y + 1
*(y + 1)
y += 2; *y
*y = 38
*y - 1
*y++ *y
y[0]
x[2] > y[0]
y - x
13 1
20 1
39 1
38 1
37 1
43 1
0 1
3 1

3. Question 2 : Fill in the blank so the code does what is desired.
1) A code that prints all characters of the string.
char ch, *str = "Hello World";
while((ch= *str++ ) != '\0')
printf("%c", ch);
2) A code that prints the elements at the even indices.
int *p, arr[] = {10,33,15,22,14};
for (p=arr; p<arr+5; p += 2 ) /* corrected */
printf("%d ", *p);
3) A code that reverses a string: char n=0, *s, *e, str[] = "siht hsinif ot ekil I";
while (str[++n]);
for(s=str, e=str+n-1; e>s ; e--,s++ ){
str[n] = *e;
*e = *s;
*s = str[n]; }
str[n] = '\0';
