7  What is the value of the indicated variable after each of the following statements?

             int a = 20, b = 18, c = 10, p = 32, q = 5, r = 0;

   a)  r = a++;       r = _____________   a = ___________

   b)  p = --b;       p = ____________   b = __________ 

   c)  c *= q;        c = _____________   q = __________


9.  You are given the following two propositions: 

p is the proposition: “eight times five equals twenty one”
q is the proposition: “six divided by three equals two”

Find the truth value of each of the following logical expressions

a)   p || q ………………………………. 

b)   p && q…………………………

c)    !(p || q)………………………..

d)   !p || !q ………………………………

e)   !p && !q……………………..

f)   !(p && q)…………………………….

10.  What is the value of the indicated variable after the following statements?


int m = 10;
int n = 25;
int l = 30;
int k = 15;
int x = 0;
int y = 2000;

a)  x = n++    x=…………………………. n = …………………………….

b)  y = -m;     y= ………………………… m=…………………………….

c)  l += k:       l=………………………….  k= …………………………….

come on no1 knows this stuff

I wish I could help you.

I may be in a IT class but we don't learn coding.

As for 7a ++ means add 1 if I'm not mistaken so in this case r and a would have the value 21.
In 7b -- means subtract 1 so p and b would have the value 17.(no guarantees)
I can't help you on 7c don't know cause I don't know what this means *=

9a is true, 9b is false, 9c is also false, 9d is true, 9e is false and 9f is true(again no guarantees)

As for 10
in 10 a x and n would have the value 26.
I don't know what a sole + and - mean in front of a variable mean, so I can't answer 10b and 10c.
Still hope this helps.

dude i think your right on this one thanks man that helps out but one thing that puzzles me though what do you put for the second line on question 7 and 10

a)  x = n++    x=26. n = 25.

b)  y = -m;     y= -10 m=10.

c)  l += k:       l=45 k=15

PS. I am a BICT graduated a year and a half ago

wow dude 

you are good.

wait wait wait... if you're professor didn't tell you anything and he's having you guys do this crap... then I would talk to your counselor about getting a diff. teacher, because that person must be messed up in da head.

yea i know exactly but he's the most qualified for the job the dudes name is joe weissmen or weissman i forgot how to spell his name and he worked at IBM for 40 years before he retired and got into teaching. he sometimes cures like a sailor and he writes like crap and their isn't another class like this so it's either this or an extra semester on top of the 11 that i need to take before graduating. if i had a choice i'd fill out the teacher evaluation saying he did crap fliped the bird at him then changed professors

and i want to do this as fast as possible so i'm doing spring, summer, & fall so i can graduate in 3 and a half years
