Well, it should work. Please share your code so we can help you.

#include &quot;cuda_runtime.h&quot;
#include &quot;device_launch_parameters.h&quot;
#include &lt;stdio.h&gt;
#include&lt;stdlib.h&gt;
int main() { char sentence[1000]; FILE *fptr;
 fptr = fopen(&quot;program.txt&quot;, &quot;w&quot;); if(fptr == NULL) { printf(&quot;Error!&quot;); exit(1); }
 printf(&quot;Enter a sentence:\n&quot;); gets(sentence);
 fprintf(fptr,&quot;%s&quot;, sentence); fclose(fptr);
}
With the same code, I get an error LNK1104: cannot open file &#39;kernel32.lib&#39;

#include "cuda\_runtime.h"

#include "device\_launch\_parameters.h"

#include <stdio.h>

#include<stdlib.h>

int main() { char sentence[1000]; FILE \*fptr;

 fptr = fopen("program.txt", "w"); if(fptr == NULL) { printf("Error!"); exit(1); }

 printf("Enter a sentence:\n"); gets(sentence);

 fprintf(fptr,"%s", sentence); fclose(fptr);

}

well.. works for me on GCC 7.1 (Windows 7 x64; target <code>x86_64-w64-mingw32</code>). How do you compile and run the program?
<pre><code>#include &lt;stdio.h&gt;
#include &lt;stdlib.h&gt;

int main() {
 char sentence[1000];
 FILE *fptr;

 fptr = fopen("program.txt", "w");
 if(fptr == NULL) { printf("Error!"); exit(1); }

 printf("Enter a sentence:\n");
 gets(sentence);

 fprintf(fptr,"%s", sentence);
 fclose(fptr);

 return 0;
}
</code></pre><pre><code>$ gcc test.c -o test.exe
$ ./test.exe
Enter a sentence:
Hello

$
</code></pre>program.txt:
<pre><code>Hello
</code></pre>

I&#39;m using Visual Studio 2012 to compile it.
I&#39;ve made a Cuda 8.0 Runtime Project.
The file extension being run is &quot;main.cu&quot;

hmm. tbh, I never used CUDA. afaik, it&#39;s running on both, the CPU and GPU. According to a quick search, the above program should work on the host side... Unfortunately, I cannot help you any further, so I really hope someone else is more knowledgeable.
