c language: I cannot find the output file.

nenyan

What is wrong with my code?

Code:

#include <stdio.h>


int
main(int argc, char *argv[])
{
	int i=0;
	FILE *fp;
	char fname[100];

	sprintf(fname,"%04X.txt",i);	
	fp=fopen("fname", "w");
	fprintf(fp, "hello world!\n");
	fclose(fp);
}

Hi nenyan!

Can you find a file named "fname" (literally)?

Or, in order to generate the file with the file name that you are expecting, you need to remove the double-quotes from around "fname" in the open statement so that you use the variable name fname and not the literal string "fname"
