reading file and strtok

**Butters007** · 12-02-2006

I have a text file that has about 50 lines of text like this:
Nancy Bush;2607 Avenue;Atlanta

I am sopossed to put it into a hashtable, but right now im just reading in the text.

My snipped of code can read the whole file in, giving me all the names, but how can i read in the street and city too? Do i just do another strtok right after the first one? (just tried it and doesnt work)

Code:

FILE *filelist;
      filelist=fopen("fileit.txt", "r");
      char line[max_string_length];
      char *name,*street,*city;

      while(fgets(line, sizeof(line), filelist)!=NULL){
         name=strtok(line,";");
         street=strtok(line,";");
         printf("%s\n",name);
         printf("%s\n",street);
      }

Have you tried
strtok(NULL,";")
for the 2nd and 3rd call?

Code:

#include <string.h>
#include <stdio.h>

int main()
{
	char line[] = "Nancy Bush;2607 Avenue;Atlanta"
		;
	char *name,*street,*city;
	name=strtok(line,";");
	street=strtok(NULL,";");
	city=strtok(NULL,";");
	
	printf("%s\n",name);
	printf("%s\n",street);
	printf("%s\n",city);
	return 0;
}

Output:

Code:

Nancy Bush
2607 Avenue
Atlanta

Code:

void strtokisforsuckers( void )
{
    FILE *fp = fopen( "yourfile", "yourmode" );
    if( fp )
    {
        char buf[ BUFSIZ ];
        struct foo bar;

        while( fgets( buf, BUFSIZ, fp ) != NULL )
        {
            if( sscanf( buf, "%[^;]%*c%[^;]%*c%[^\n]%*c", bar.name, bar.addy, bar.city ) == 3 )
                printf("%s\n%s\n%s\n", bar.name, bar.addy, bar.city );
        }

        fclose( fp );
    }
}

sscanf( "%[^,]%[^;]%[^\n]",

should be
sscanf( "%[^;]%[^;]%[^\n]",

because the first delimiter is also ; not ,

**quzah** · 12-02-2006

Yeah, and I left out the first argument. I thought he was delimiting with a , the first time and a ; the second. It also needs a few minor corrections, to get rid of the ;, which I've added. This, kiddies, is why you should use your preview button and not just type as you go, like I do.

also some typo
sscanf( buf, "%[^;]%*c%[^;]%*c%[^\n]%*c",
red - mandatory moved
blue - optional, can be removed

Yeah you caught me in mid-edit. I tend to just hit edit over and over and use "save" instead of preview.
