double to txt file

[studentffm]

Hi, I want to save the value of a variable in a txt file, but when open the file to see the result it is empty

I have the following code:

#if defined(WIN32)
err_averages;
FILE *f_averages
char output_averages[200];
err_averages   = fopen_s(&f_averages, output_averages, "w");
double averages[3] = {average_sv, average_svj, average_svcj};
char[50] = "E:\\";
sprintf_s(output_averages, 50, "%s\\results\\averages.txt",mainpath);

		for (int s=0; s<3; s++)
		{
		averages[s];
			fprintf(f_averages, "%15.6", average[s]);
			fprintf(f_averages,"\n");
}
fclose(f_averages)

10x for the help

Well for starters you dont declare a variable at line 7...

Sorry.. it is actually declared... I missed it when I wrothe the code in the forum

It is so:

char mainpath[50] = "E:\\

I do not get compile error

P.S. ...fixed..
