Question

hey pplll.plz help me with this one .........1-d

Answer 1

What's the main problem you're having?

Answer 2

find the answwer of 1-d

Answer 3

void calc(int &a, int b) {
cout << a << "\t" << b << endl;
a = b++;
b = a++;
cout << a << "\t" << b << endl;
}

void main() {
int x = 5;
calc(x++, ++x);
cout << x << endl;
}
that one?

Answer 4

yes...

Answer 5

i know this is easy ques...but i suck in c++ coz f ma tchr

Answer 6

it's a pretty tricky questions =P

so when the program enters calc what would the values and a and b be?

Answer 7

no idea,...

Answer 8

so to begin with x = 5

when you call calc(x++, ++x)
x will be incremented before the function and after
x = 6

calc effectively gets called with a = 6 and b = 6
this is before a is a reference of x

so the first output would be
6 6

Answer 9

make sense?

Answer 10

it does.....

Answer 11

i suppose u r right

Answer 12

awesome do you think you could do the rest now or still a little stuck?

Answer 13

and the second part..

Answer 14

7 8 ?

Answer 15

almost

a = b++; // b is 6 so now a and x are 6, remember this is a post increment
b = a++; // a is 6 so now b is 6 and a and x are 7

So the output should be
7 6

Answer 16

okiezz..thanks...and can u answer 1e and 1f

Answer 21

ok i see now, with 1f

you have
x = 725
y = 245

a is between 4 and 6 (i'm assuming the random function returns [0, n) )
b is between 2 and 3

do you think you could do this one now?

Answer 22

i said naa.....my c++ 'll improve only aftr a month....oz now i 've joined a coaching class....so plz help me today...:(

Answer 23

for 1f the answer would be a)

and 1e
the first for loop is working out the length of the string.
c strings are terminated by a '\0'

the second loop is looping from 0 to the middle of the word

and if statement is looking for capital A's and E's
since there are no A's or E's in the first half this wont ever happen

and in the else it's swapping characters, eg first with last, second with second last etc
so the result would be a word that is reversed if it doesn't have any A's or E's in the first half of the word

PreboardExam would become
maxEbraoberP

Answer 24

hopefully that all makes sense

good luck with the c++ =)

Answer 25

tnx a lot...:)
