Question

I’m basically trying to make this code work in windows and I have to use the sprint() and writefile() functions included in the windows API. I’m a little confused as to how to go about this, the windows C code seems a lot more complicated.

#include <stdio.h>
#include <string.h>
//Defining String used for name//
#define NAME "Rodger Rodger"
Main(){
char tbuf[35];
memset(tbuf, '\b', sizeof(tbuf));
sprintf(&tbuf[0], "Hello %s\n", NAME);
write(1,tbuf,sizeof(tbuf));
}

Output: Hello Rodger Rodger

This works however I need to do it in Windows using the writefile() and sprint() functions.

EDIT: Managed to do it in the end. This is the final code:

//C Programming in Windows //
//Timothy Ford //
#include  <stdio.h>
#include <windows.h>


//Defining String used for name//
#define NAME "Timothy Ford"

int main(){
char tbuf[35];

//Handle used to define output
HANDLE Outta = GetStdHandle (STD_OUTPUT_HANDLE);

//DWORD used to store bytesWritten
DWORD written;

memset(tbuf, '\0', sizeof(tbuf));
sprintf(tbuf,"Hello %s\n", NAME);

//WriteFile used for output of string
WriteFile(Outta, tbuf, sizeof(tbuf), &written, NULL);


return 0;
}

I notice several problems with your code:

• Don’t pass the address of tbuf[0] to sprintf. Instead pass tbuf. Tbuf is already a pointer to character string: sprintf(tbuf, "Hello, %s\n", NAME);. Not that it will not work as is but I think the version I propose is both shorter and clearer.

• Why are you memsetting tbuf to ‘\b’? This is backspace while I believe you want to set tbuf to 0(‘\0’)

Here is the working version on ideone.
