Can you help me with these AP Computer Science Questions. (THIS IS DUE BY 1:30 PM today) you have to evaluate the Boolean Expres

vfiekz [6]

Answer + Explanation:

'and' -> both statements are 'True' to evaluate as 'True'.

'or' -> at least one statement is 'True' to evaluate as 'True'.

1. True (grade has the value of 82, so the statement evaluates to 'True').

2. True (Both statements are true, this expression evaluates to 'True').

3. False (Both statements are false, this expression evaluates to 'False').

4. True (the != operator means <em>not equal.</em> Since the 'name' variable holds the string 'Rumpelstiltskin', name != 'Rumpelstiltskin' evaluates to 'False'. The 'not' operator returns the opposite of the given Boolean expression, so this expression evaluates to 'True').

5. True (name == 'Rumpelstiltskin' evaluates to 'True', so this expression is true).

6. False (All statements evaluate to 'False').

7. True (All statements evaluate to 'True').

8. False (All statements evaluate to 'True' except for <em>not(x == - 3) </em>which evaluates to 'False', so the whole statement now becomes false).

9. True (<em>grade+5 < 90 and grade >= 80 </em>evaluates to 'True', so this whole expression becomes true).

10. True (<em>grade > 0 and x % 2 == 1 </em>evaluates to 'True')

Hope this helps :)

for(int i=0; i<len; i=i+2){

a[i]=a[i+1];

a[i+1]=a[i];

int[] b={a[i]+a[i+1]};

}

if(len%2 !=0){

for(int j=0; j<len; j=j+2){

a[j]=a[j+1];

a[j+1]=a[j];

a[len-1]=a[len-1];

int[] b={a[j]+a[j+1]+a[len-1]};
