If you have writtern the code , you would not need someone else to make you understand what is going on .

Try g++ -Wall file.c , I guess some of the apis you are using does not work with g++ .

You need to learn postfix notation and use a stack to evaluate an expression , kerninghan and rithie C book has got code for basic calculator.

Check if heapalloc is failing.

That is quite simple , give it a try , you can finish it in an hour.

Use argc and argv .

if(str1[i]==str2)

This line is error prone.

There are programming lanuguages written specifically for AI , e.g. LISP, C++ is not that suitable for AI, better try some easier topic for your project assignment.

If you initialize all objects in their constructors , those objects which got initialized, destructor will get called as well.

Include path of what ? I guess you need to add it in your makefile.

You can use minix and modify source code here and there , you will never be able to write a new OS code yourself.

But why do you need vector of vectors ?

Yes I guess , also you might need to change name of the executable in html file.

Buying the C++ book by stroustrup and doing all the exercises will serve same purpose.

Define all the constructors.

No you cannot convert , are you looking for something like this ?

char *a="hellp";
char b = *a ;

I guess you need to pass filename.c_str() .

You can also use template if it is allowed for your homework however.

You cannot compare string like that use functions like compare ,etc.

I could use netsnmp from sourceforge successfully for unix.

term += 1/(x*(x+1));
or
term = 1/(x*(x+1));
?

I hope this is a C++ project assignment, you are not using c++ types like std::string which could simplify your coding.

Except for the facts like C++ has more keywords, so int new; will not compile in C++, but it will work without any problem in C.

In .txt , read the text file using fstream

Try to implement some difficult algorithm, pick something like image processing, etc, also check sourceforge.net however do not copy and submit it as your project assignment.

This is probably the shortest piece of C++ code ever written by someone :)

You can keep the question and answer in afile and read from it.

You can find such library at sourceforge.net

use abs .

3(3(3(3x+1)+1)+1)+1 < 500

Can you not use the string apis ?

Download something from sourceforge, if you can understand the code, modify each lines of code and then submit it as your homework, if you cannot understand it, you might get caught. So it is better...

Rather posts the portion of the code which is giving you trouble, and also detail the problem that you are facing.

You have to write it as a window service.

I think the C++ book "Thinking in C++ " available online, just search it in google.

Use >> in lieu of getline (it is not a C++ function)

where have you defined delete?

use substring.

I think only book you will ever require is C++ by Bjarne Stroustrup.

Yes use pow(abs(n) ) *abs(n)/n
