Thread: Retaining same amount of digits

Well, I have a number that I wish to stay at four digits and I have no idea as to how to keep an integer stick to such a scheme.

Code:

#include <stdio.h>

int main(void)
{
    int number = 0000;
	for ( ; number < 1000 ; number++)
    {
        printf("&#37;d\n", number);
    }

    return 0;

}

It should come out like this;

Code:

0000
0001
0002
0003
0004
0005
0006
0007
0008
0009
0010

Yet it comes out like this;

Code:

1
2
3
4
5
6
7
8
9
10

Any assistance would be appreciated

Try using "%04d" instead of just "%d"

Worked great Thank you to all who answered my question! I have one last one before I run off into the shadows :P How do I implement this with a WinAPI? (e.g. MessageBoxA)

Use sprintf() to format the data into a string like this:

Code:

char digits[5]; /* Space for 4 digits plus null terminator */
sprintf(digits, "%04d", value);

Then pass the "digits" string to the message box call.

Doesn't work, thanks for the replies however

Code:

sprintf(buff, "%04d", spam);
PostMessage((HWND) msWin, WM_CHAR, buff,(LPARAM)0);

invalid conversion from `char*' to `WPARAM'
initializing argument 3 of `BOOL PostMessageA(HWND__*, UINT, WPARAM, LPARAM)'

Thanks again zacs7! (second time you've helped me)

Now the code parses correctly with no errors but it doesn't actually output anything :P

Code:

#include <stdio.h>
#include <windows.h>

HANDLE msWin;

DWORD pID = 0;
DWORD buf = 0;
DWORD memAddr = 0x007D4E28;

int main(void)
{
    int number = 0000;
    printf("Enter the number at which you wish to start at\n");
    scanf("&#37;04d", &number);
    HWND mWin = FindWindow(NULL, "Untitled - Notepad");
    if(mWin) {
             printf("Started spamming.\n");
             char buff[5];
             DWORD wTP = GetWindowThreadProcessId(mWin, &pID);
             msWin = OpenProcess(PROCESS_ALL_ACCESS, 0, pID);
             for (; number < 9999 ;)
             {
             Sleep(10);
             ReadProcessMemory(msWin, (LPVOID)memAddr, (LPVOID)&buf, 2, NULL);
             if ( buf != 0 ) {
                      printf("Died?");
                      system("PAUSE");
                      }
             else {  
                      sprintf(buff, "%04d", number);
                      PostMessage((HWND) msWin, WM_CHAR, (WPARAM) (char *)buff, (LPARAM) 0);
                      PostMessage((HWND) msWin, WM_CHAR, VK_RETURN,(LPARAM)0);    
                      number =+ 1;
             }
             }
    else {
         printf("Victim not found D:\n");
         system("PAUSE");
         return 0;
         }
}

Any ideas?

zacs7, thanks for you ongoing support but it appears I made a typo :P

The program doesn't input anything into the window/application I specified.

I'm pretty sure it isn't, nonetheless I think I have pin-pointed my problem. Will be back to tell results D:

zacs7, I plan to make a small program that will combat my friend's program :P (reasoning behind it)

I noticed a small but in the dialog which was having messages posted to it. (msWin to mWin) I still have the same problems however
