How does C write data to an EXE file?

This can be achieved under Windows 98, but not with the NT kernel. If you want to write data, save it to ini or registry.

As follows: include

using namespace std;

#include

Contains a file stream header file.

#include

int main()

fstream datafile;

Define the file operand. ,ios::out);Create a file if(!datafile)

Check whether the file is created.

cout<<"error

open"datafile<<"jjhshhs";

Write data to a file.

datafile<<"dhjhjhsj";

Close the file. If the file is not closed, the data will not be written. Because there is an input buffer.

system("pause");

return 0;

I have two ways to do this...

The first one needs to change the source**, the second one doesn't; Often, the first method is used to write it yourself, the second is used to check others, but the second one is a bit of a hassle...

Under Linux, it can be implemented using the "Command < Input File".

But I'm not sure on Windows, so I guess it's okay.

Guess is that you didn't close when you compiled. exe file.

In fact, this is very simple, I have also appeared, c language path do not use Chinese characters, otherwise the compilation can not find the path. You try, it should be like this! ~

The exe file is a hexadecimal executable file.

If you want, you can use a device that supports hex, flexhex, winhex, minihex, etc.

Open the hexadecimal.

Browse and open the pending hexadecimal file.

Once found, double-click in the relevant location to display the Modify dialog box, and enter the value to be modified. Hexadecimal input can usually be selected, or character input can be selected.

After saving.

#include

void main()

The path of its Chinese document is changed by itself, and by the way, the file being executed cannot be modified. So there's no way to write 0 on this file.

You can right-click on the exe file Kisen Mill, select "Properties", and then click the "Security" tab.

You can delete "everyone" and set your own spring carrier permission to "read and run". Now that you already know the permissions to change folders, I won't talk much about the permissions of files, almost.

1.Add a tag or box component to your program that can be visually set to false.

2.Write 123456789 in a tag or box and compile.

3.The compiled program is then converted into a byte set in software.

4.Convert 123456789 to byte sets.

5.Convert your email address into a byte set 1234567896Suppose the program converts the byte set to x 123456789 converts the byte set to c, and the email address converts to the byte set to v

7.Replace the c in x with v

8.Save the modified file.
