Quote: 1.
Write C Programs to
a) Find the reverse of an integer value recursively.
b) Print all prime numbers less than N, where N is an integer given by the user.
Define and use a function prime(x) that checks if a number is prime or not.
c) Search for a Key in a 2D array. If the key is in the array, return its position also.
d) Read two unsorted list of numbers. Sort the lists individually and finally merge the two lists to form a single sorted list. Define and use function readlist(l) to read list l and sort(l) to sort the list l.
e) To read two square matrices and check whether multiplication of these matrices is commutative or not.
2. Write a menu driven C program to operate on Strings.
Menu:
Key
Action
**************************************************************
1 Print String Length
2 reverse string
3 convert all characters to lowercase
4 convert all characters to uppercase
Implement each action using User defined functions.

Short answer: No.
Longer answer: These forums are for people who want assistance with the code that they have written. They are not here for someone else to do your work or homework for you.

Pick yourself up and write it! A degree in software engineering without background knowledge is less valuable then a roll of toilet paper. Such a degree helps you to get only positions like "seller in McDonalds"... Think about it and either start learning programming quickly or in case of disinterest towards software engineering find something else and change your profession/course.

Given a month and year, I want to write C++ code to determine what day of the week the month starts at. For example, for 2/2013, I want the code to return Friday (or an integer representing Friday) because February 1, 2013 was a Friday. The code needs to be portable. What is the best way to do this?
Thanks
Bob

Something like the following, with maybe a tweak or three:
struct tm time_in = { 0, 0, 0, 1, 7, 2013 - 1900 };
time_t time_out = mktime(&time_in);
struct tm *time_local = localtime(&time_out);
_tprintf(_T("%u\n"), time_local->tm_wday);

Nice idea, but the OP was looking for something portable.

I would suggest converting the date to a Julian Day Number. Here is a function we use to convert day, month and year to such a number. The input values (D, M, Y) are all unsigned int.
unsigned int yh = Y;
unsigned long c, ya, j;
if (M > 2)
{
M -= 3; }else{
M += 9;
Y--;
}
c = Y / 100;
ya = Y - 100*c;
j = ((146097*c)>>2) + ((1461*ya)>>2) + (153*M + 2)/5 + D;
Using that you just need the Julian Day Number corresponding to a date for which you know the day of week as a reference. You can then subtract the numbers to get the days in between.
Please note that the function is only valid from 14th September 1752 (when the Gregorian calendar started).
The good thing about pessimism is, that you are always either right or pleasently surprised.

Question 1. Read two unsorted list of numbers. Sort the lists individually and finally merge the two lists to form a single sorted list. Define and use function readlist(l) to read list l and sort(l) to sort the list l.
Question 2. To read two square matrices and check whether multiplication of these matrices is commutative or not.

You are knocking on the wrong door. This is not a site that writes the homework of students. These questions are far from being serious enough to waste the free time of a programmer. You should have enough free time for this as currently your full-time work is learning programming by completing these simple and boring tasks. Also please read my advice: here[^].

How can I get address of current page in Firefox?
|
|
|
|

Its address in memory? Is this a C/C++/MFC question?

thanks for your answer. It is obvious that it resides in memory
but how can I find its address. furthermore I think that it is
related to C/C++. take it easy. 
|
|
|
|
|
|
thanks for your favor. If writing an add-on is intended, it is true
but I don't want to write an add-on. I just want to manipulate it
from outside.

You could try to get the process handle of Firefox and from that, get the handle of the windows (HWND) and enumerate the child windows to find the one containing the address bar and do a GetWindowText on that child window.
A quick look with Spy++ does not help finding the address bar window (or edit box) so it might be more involved than that
good luck.
I'd rather be phishing!

It doesn't work. Elements in Firefox aren't standard windows element. They are handled by firefox. try SPY++ to see what I
am talking about.

Hi all. Suppose a BaseClass has two childs. Now when the childrens' constructors are called, the base class' constructor is also called. Here is the scenario, in code.
class BaseClass
{};
class ChildOne : public BaseClass
{
public ChildOne(){}
};
Class ChildTwo : public BaseClass
{
public ChildTwo(){}
};
Do the childs share the same parent instance? I wanted to know a little more deep information about BaseClass instance and the two child instances. Thanks
This world is going to explode due to international politics, SOON.

No, if you create two separate instances of the child class, then you also get two separate instances of the base class.
But, of course, any static members are shared between all instances of the base and/or the child class.
The difficult we do right away...
...the impossible takes slightly longer.
