ive been trying to get my program to work all day parameter 3 on CopyFile is the problem i think
Code:#include <iostream> #include <windows.h> #include <cstring> using namespace std; int main() { for(int i=0;i<2;i++) { char buffer[50]; itoa(i,buffer,10); strcat(buffer,".exe"); CopyFile("Install1.exe",buffer,0); } }
In future, be a lot more specific, both in your subject line, and in what exactly the problem is. Look up the copyfile function on MSDN (http://msdn.microsoft.com/library/de...e/copyfile.asp). That should clarify your confusion about the parameters.
>> parameter 3 on CopyFile is the problem i think
the first thing you need to do is find a good reference. "If this parameter is FALSE and the new file already exists, the function overwrites the existing file and succeeds". my guess is that the current directory is not set to the directory you have the original file.

beat me to it

Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
Another problem i had once with the strcat() command, if the char isn't defined yet sometimes the strcat works and sometimes it doesn't try using strcpy(). I hope this helps!
Do you know of any good references that i can look up functions as i need them?

If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
i seem to have GCC 3.3.4
But how do i start it?
I dont have a menu for it or anything.
