Creating Files for Writing Only
Creating Files for Writing Only : To create a text file for writing only, pass "w" into fopen as the second argument. This example follows along the same lines as the previous:
#include
int main()
{
FILE *file; /* declare a FILE pointer */
file = fopen("data/writing.dat", "w");
/* create a text file for writing */
if(file==NULL)
}
else
printf("Error: can't create file.\n");
/* fclose(file); DON'T PASS A NULL POINTER TO fclose !! */
return 1;
printf("File created. Now closing it...\n");
fclose(file);
return 0;
Now, if I went into my data folder, I could see a text file called "writing" was created. However, if my data folder didn't exist, an error would occur.
