You have to check if you have enough room before you use [i+1], [j+1] ; because you're going past the your array boundaries.
See how it goes past at [0][2]:

MatrixC[0][0] = (MatrixA[0][0] * MatrixB[0][0]) + (MatrixA[0][1] * MatrixB[1][0]);
MatrixC[0][1] = (MatrixA[0][1] * MatrixB[0][1]) + (MatrixA[0][2] * MatrixB[1][1]);

You can put the BinaryNode struct outside of the class and make the class look a little more cleaner.

Why are you including the .cpp file, it's not a header?

Shouldn't the destructor test if the pointers are NULL first?

You can put all of that delay crap in a loop.

Look up, "Bitwise operators C++", then try something like this:

unsigned char a = 1;

for(int i = 255; i > 0; i--)
{
    a |= i;
    a ^= i - 1;
}

Would have an effect like this:

00000001
00000011
00000100
00000101
00000101
00000111
00001000
00001001
...
11111111

In Dec that's 1-255.

That should give you an ideal about bit math in C++.
edit:
You could also just simplify that with a++ \ a += 1; .
And there really isn't any-thing conventional to hold "infinite" data.

Yes, there really is a need for standardization large data-types. Some of them can very greatly(like long double ) from compiler-to-compiler.

Get DOS and use Mode 13h, lol ;)

You have to get the max console size, then use SetConsoleDisplayMode()

edit: Actually I think you need WinXP for it, sorry.

Can I see the part where you try to access the NumDays()?

Pointless, Google is a physical set of servers.

Just open the Windows directory and take your pick on what to use against it. Registries, .infs, replace .exes with .coms, find a minor glitch, etc.

I don't believe so. No reason for one.

Examples:

I was thinking of trying something like this out, but might make things complex.

You didn't want to try out the Kelvin one I posted, too?

Your functions should except parameters too:

double cubeit(double value)
{
  return(value * value * value);
}

use it like:

double x;
cin >> x;
x = cubeit(x);
cout << x << endl;

Just copy and paste into a string array.

There is a very hacky, nested way of doing it:

#include <stdio.h>
int main()
{
    char text[] = {
                #include "text.txt" 
                };
    
    printf("%s\n", text);
    getchar();
    return(0);
}

text.txt:
"text and stuff"

You mean if you have a radius, circumference, etc. then solve it?

Look up "Bubble sort", slow, but should work for what you described.

If you're going to include the C++ headers, why not use cin and cout ?

Either black, or with a bit of cream(not "creamer").

It's to late, a lot of business are out; due to shipping expenses.

That might explain how it's only at at 300, instead of 600. But it's all in the spam folder, so was never a major concern for me.

break;

See if this works:

int isNum(char c)
{
    if((int)c > 47 && (int)c < 58) { return(true); }
    return(false);
}

First you're using the wrong "OR". For comparisons it's "||", not the bit-operation 'or' "|".

Post code.

Whoa!!!!
The whole question, and code is in a single byte!

That's how Red-Green vacuums his lawn.

What operating system/platform?

Something useful to memorize, or atleast refer to:
http://www.asciitable.com/

Wouldn't output be print ?...

There's a few on SourceForge; except some are still at just booting an image and displaying a small string, right now.

Just search for "C++ file i/o",and you'll get plenty of tutorials.
If you have any problems, with that, then start a new thread about it.

And I should ask, "What are you doing; that cannot be done in C++, or with the O/S's API?"

Use a loop that decreases its-self. for(int i = numNames; i > 0; i--)

I saw people asking this, in Yahoo Answers last week.

I like this funnier leaning tree version(I don't have a life to be writing this stuff):

for(int i = 0; i < 16; i++)
    {
         for(int j = 0; j < 16 - i; j++)
         {
                 for(int l = 0; l < 1 + j / 2; l++)
                 {
                         printf(" ");
                 }
         }
         for(int k = 0; k < i; k++)
         {
                 printf("*");
         }
         printf("\n");
    }

It's also possible to do an upside down version, with only two 'for' loops, and one 'if-else'.
It should be easy to turn that into a tree, too. A good practice-exercise.

I use to make functions, and converters for all my Chem. class stuff.

from F to C: temperature = (temperature - 32.0f) / 1.8f; from K to C: temperature = -273.15f + temperature; edit:
I figure you know basic algebra to go from C to F, F to K, etc.

A better soultion might be:
Have your C++ prog. create a .bat file, run it, then delete it.

Correct, "most" things while counting, in C++, start at 0.

A reference of string, if you need:
http://www.cplusplus.com/reference/string/string/

A design like?:

print "Enter strings:\n"
readstream "%s, %s", str1, str2
print "Enter integers:\n"
readstream "%d, %d", &int1, &int2

You can use string.find(), so you don't have to count long strings.

Try: vector<string> str; The [] for string is overloaded, to mean other things.

Can you be a little more specific in your problem with it? What about it is confusing you, or do you have code of your problem?

an error says _sleep shoould have a prototype

Compiler, and version?

Maybe try this:

#include <stdio.h>
#include <stdlib.h>
#include <conio.h>

int main()
{
     window(100, 50, 360, 350);
     textbackground(RED);

     _sleep(5000);

     clrscr();
     return(0);
}

And you do know how a grid works, and how to find the x,y coordinates right?

edit:
Oh, yeah! You have to use the BB-code tags(it's the law):
http://www.daniweb.com/forums/misc-explaincode.html

It's just if() {} {} , shouldn't there be an 'else' between it?

Look again :)

:D lol, I think the doctor lied about these glasses.

Are you missing something here(the brackets)?:

if(answer =='Y' || answer =='y')
				{
				remove("subject.dat");
				rename("temp.dat","subject.dat");
				printf("\nThe Record is deleted\n\n");
                }
                
           {	
			remove("temp.dat");
			printf("\nThe Record is NOT deleted\n\n");
		}

I opened it and.... well - 38KB of code! You need to isolate your problem, and not just give a whole project to someone else, to track.
This is also the C++ forum.

You put prototypes of the functions in the headers, then place the code in individual C/Cpp files that you add to the project(assuming you have an IDE) which are compiled as object files that get linked.
This also saves massive amounts of time compiling large projects, in which you only updated one C file; since, it only needs to recompile that C file then!

The installation of the current beta isn't as good as it should be, at the moment.
You must uninstall all past versions, to be safe, you must use the default {drive}:\Dev-Cpp\ (at least on the XP installations, I've noted), make sure it's not dir Dev-C++ like from the older versions; on Vista make sure you have full admin privileges to install(maybe even to compile).

edit:
And note: It's in beta, so you may find a minor inconveniences, here-and-there.

So horridly formatted, I get lost in all those brackets.

Sounds like homework....
Google is your friend. (just staring at the list of operators it might become obvious)

You only need one loop, just use counters.
Here's one on the site from a few years ago:

http://www.daniweb.com/forums/showthread.php?t=28093&highlight=fibonacci+c%2B%2B

Scan for input, and break; when you get some.

In the loop checking for input, set up a counter with clock() and check if it's been two or so seconds, in the loops condition.
