>Can somebody simply the function for me plz. You mean explaining it?

Please be specific. No one has time to look at your 1MB code and point out the error.

Keep it simple. You should perhaps say that you want to write a parser. I guess you already have made the [B]stack[/B] class. At any point of time the comparison operator works with characters too.

The error is definitely right. You are using uninitialized [I]d[/I] and [I]c[/I]. So what to do? Look at the defination of [CODE]AltMoney read_money() { [B] [COLOR="Red"] int d, c;[/COLOR][/B] cout << "Enter dollar \n"; cin >> d; cout << "Enter cents \n"; cin >> c; blah blah }[/CODE] I think …

>can't quite figure out how to get the queue to appear on screen. [B]Complete the queue::print() function.[/B] First of all, make print() a member function of the class. In the print () function, you should simply print your main data array which is. int a[SIZE]; from front to rear with …

The code tags are [[B]CODE=c++[/B]][[B]/CODE[/B]]. You are getting the error because you are redefining myfile at two places: first as ifstream and then as ofstream which is illegal. use fstream instead as: [CODE] fstream myfile; myfile.open(filename); [/CODE] As I can see, your array is of type double. getline() works only …

There is a much better way: Just add a [icode]i--[/icode] in the body of the if statement; [code=c++] for (int i = 0; i < inp.length(); i++) { if (inp[i] == '~') { inp.erase(i, 1); i--; } } [/code] And it works like charm. I dont know why are you …

You can use system() function and issue a copy command. I don't know what are the alternative. But this will definitively work.

You have any idea what are you asking? We don't know you, nor your ability, nor that how much time you have, not how much brains you have. We know nothing of you then how can we tell what is a "mini" project for you. Mini can be a Hello …

When a file is opened is in Text Mode, the operating system's new-line character is auto-magically converted to the standard '\n'. >Not sure what MAC uses. BTW Mac uses "\r".

If you are a learner and still in basic stage, I prefer you write your own class about Date and overload the comparison operator, and then work with them.

First of all read this link -> [url]http://www.parashift.com/c++-faq-lite/operator-overloading.html[/url] and come back. BTW a short answer to why we use operator overloading is so that our class have a intuitive …

Why the heck you are using cstrings. They are old, they are evil and they can lead you in trouble. Use std::string and be happy in life.

Point 1: n*(n+1)/2 is even valid for n=1, so you don't need a degenerate case of n=1. Point 2: as vmanes said, your base case is good, but look at your recursive case: [ICODE]return (n+sum(n+1))[/ICODE] Try to think what would happen if I call sum(2)? it would return 2+sum(2+1) which …

Create a static member in your class which is a bool type 2D array (call it say,[B]current_pos[/B]) of 8X8 elements. Each time you assign a Position to the object, be sure to mark the current_pos[x][y]=TRUE; So, now you can keep track of what all postition are been ocupied. Hence, as …

[ICODE]if (gmOption == 1)[/ICODE] change it to '1' not 1 since gmOption is a char not a int. [CODE]cin >> cheat; if (cheat == 236)[/CODE] I think the cheat is 236 right? So it should be a string. Define your cheat as[ICODE] char cheat[3[/ICODE]] and not simply as a char …

What a crap this code is...........? And you say you just want it to compile.!! Read your text book first.

Wow, a zig-zag flow of control. But is definitely not a wow. Sit down with a pencil-paper and design a flow chart of your program. The flow of program is not efficient. main calls read/write which calls haha which can in turn call read/write and so on. This is definitely …

n^3 + (3n^2+2^n+1)^3 + (3n^3+3n^2+2^n)^3 = (3n^3+3n^2+2^n+1)^3 In the above equation, put different value of n=1,2,3,4,...... and you get the quadruplets.

Look at your for loop. Mathematics says that you just need to check it till [B]i<=sqrt(n) [/B]i.e. the square root of n. That is, it your input number is 33, then just check that if should not be divisible by any number from 2 to sqrt(33) which is 5. So …

You are actually doing crime here but letting the compiler generate the copy constructor and the assignment operator, Look closely what [ICODE]Inst = A(4);[/ICODE] do(sorry Comatose, I am answering that): On the right side of the assignment operator, a temporary object is created, a copy constructor is called which copy …

A quick point to note is that g++(and other compiler that support c99) allow VLA(Variable Length Arrays), if which you can specify a variable as the length of the array. i.e. the following statement are valid [code] int a,b; cin>>a>>b; int arr[a][b]; [/code] But then, the C99 standards are not …

I agree with, VernonDozier. cin>> is already overloaded for you to input the right thing. cin.get is a unformated input function. It does not format the input accordingly. It is just used for char heres the prototype [code]get ( char* s, streamsize n );[/code]
