thank you very much, i will play with this code and see what i can do with this new information.
you said you multiplied by 8, but i see only 3 could you explain this, if it was a typo then never mind

i figured out what you meant by multiply by 8, it would be 2^3 which is 8 and what i seen in your code was 3. it seems this is a cool way to multiply and divide
i hope this thread helps someone else learn something new as i did, thanks

There are many ways to do this. To use what you already have, add:
char s[128] = { '\0' };
int x = 0;
while (num)
{
s[x] = (num & 1) ? '1' : '0';
num = num / 2;
x++;
}
cout << strrev(s) << endl;

its funny i was reading about arrays today and ways to reverse the output, had nothing yet, but i did learn how to make an array. what header files did you use? when i compile your modification to my code i get an unrecognizable output.
thank you.
#include "stdafx.h"
#include <iostream>
using namespace std;
int main()
{
char s[128];
int x = 0;
int num =53
while (num)
{
s[x] = (num & 1) ? '1' : '0';
num = num / 2;
}
cout << strrev(s) << endl;
system("pause");
return 0;
}

Have you used the debugger to step through the code watching s and num?

{
int uglylist[1500];
uglylist[0]=1;
int maximum;
int max2=0;
int max3=0;
int max5=0;
for(int i = 1; i<1500; i++)
{
maximum =uglylist[i-1];
for(int j=0;j<=i;j++)
{
if (uglylist[i]>max2)
{
max2=uglylist[j]*2;
break ;
}
if (uglylist[i]>max3)
{
max3=uglylist[j]*3;
break ;
}
if (uglylist[i]>max5)
{
max5=uglylist[j]*5;
break ;
}
uglylist[i]=min(max2,min(max3,max5));
}
}
cout<<uglylist[1500-1]<<endl;
}
So Would U plz help ?

No. You have written some code, however your algorithm is flawed.

Have you used the debugger to step through the code? Narrow the problem down from 1,500 to something more manageable.

you need to close the { in that last switch
|
|
|
|
|
You also forgot to close braces after while(1)
(add another after the translate,dispatch pair)
|
|
|
|
|
Could you show me on the code where to place the { symbol as I am kinda struggling to locate it.
If you can create quick snippet of the part of the code so I can just copy that fix into my source code.
Thanks

Sure thing.
There's actually another one that neither of us mentioned yet too - you mean WM_DESTROY, not WM_DESTORY
Substitute part of your code for this:
while (1)
{
if (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))
{
if (msg.message == WM_QUIT)
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
return (int) msg.wParam;
}
LRESULT CALLBACK WindowEvent(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
switch (message)
{
case WM_DESTROY:
PostQuitMessage(0);
return 0;
break;
}
return DefWindowProc(hWnd, message, wParam, lParam);
}
There's other things amiss too, though this will give you a window that opens.

If you are using VS6, click Ctrl+] to locate matching braces (which will indirectly show you unmatched braces). I know there's a similar way in VS200x, but I don't know it off the top of my head.

I've seen functions defined as:
int SetIniString(int nConfigSet, char *Section, char *Key, const char *format, ... );
Could someone explain what the '...' in the parameter list means and does?
|

Thank you David, for the explanation and link!

Paul Belikian wrote: Could someone explain what the '...' in the parameter list means and does?
It means that the function also accepts zero or more parameters following the last named parameter. The function will then use some information passed by the caller (in this case the %x specifications in the format string) and the va_arg[^] functions, to access the extra parameters.
