Thread: Storing in structure

Hi everyone, right, I have a program that reads char strings in from a tab delimited file, I can do this. I now want the program to store part of this data(the char strings) as one of the fields in a data structure, there is an array of these data strutures. The program must also recognise when a duplicate char string has been read in, and hence not store this value. My code to date follows:

Code:

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

int main(void)
{

struct node_data			/*This is the data structure that will contain	*/
{					/*the information regarding each node		*/
char name[30];
int code_name;
int relax;
int value;
int previous_nodes[100];
};

int i, j, k, l, m;

char *sub_string;

  char line[100];

FILE *stream;

struct node_data nodes[100];		/*Declaring an array of nodes with 100 spaces*/
for(k=1;k<100;k++)
{
for(l=0;l<30;l++)
{
nodes[k].name[l] = NULL;
}
}


if( (stream = fopen( "ukcities.txt", "r" )) != NULL )
{
	if( fgets(line, 100, stream ) == NULL)
	{
	        printf( "fgets error\n" );
	}
	else
	


	{
		printf("%s\n", strtok(line, "	"));
	
		while ( (sub_string=strtok(NULL, "	")) != NULL)
		{
		printf("%s\n", sub_string);
		}
	
		for(i=1;i<100;i++)
		{

		if( fgets(line, 100, stream ) == NULL)
		break;
		else
{

		
			printf("%s\n", strtok(line, "	"));
     	 		while ( (sub_string=strtok(NULL, "	")) != NULL)
			{
				printf("%s\n", sub_string);
			}
				
		}

	
	}
	}
		fclose(stream);
	}


}

Thankyou!!
