Hi guys, this is my first post here Hope you can help me out with the problem I have...
I'm trying to create a text file with a variabe filename. My idea was to use the time from this function:
Code:
/* time example */
#include <stdio.h>
#include <time.h>
int main ()
{
time_t seconds;
seconds = time (NULL);
printf ("%ld hours since January 1, 1970", seconds/3600);
return 0;
}
as the filename, according to this function:
Code:
#include "stdio.h"
File Input/Output C Tutorial 10-5
main( )
{
FILE *fp1;
char oneword[100],filename[25];
char *c;
printf("enter filename -> ");
scanf("%s",filename); /* read the desired filename */
fp1 = fopen(filename,"r");
do {
c = fgets(oneword,100,fp1); /* get one line from the file */
if (c != NULL)
printf("%s",oneword); /* display it on the monitor */
} while (c != NULL); /* repeat until NULL */
fclose(fp1);
}
Now this is what I got so far:
Code:
FILE *stream;
time_t seconds;
seconds = time (NULL);
stream = fopen(seconds, "w");
But when I compile this, I get the error that Im doing an "Invalid conversion from time_t to const_char.
Has anyone got an idea how to solve this? Any help is highly appreciated, thanks in advance.
