I have this text, which represent (for example): date -> 2014-02-13T06:20:00 humid rate -> 4.0

At first, I want to have as an output date \n humid rate \n date \n humid rate etc. etc.. I've tried to use strtok, but i couldn't do much.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define LINESIZE 128

int main()
{
    FILE *fp = fopen("tempm.txt", "r");
    char line[LINESIZE];
    char *value;

    while(fgets(line, sizeof(line), fp))
    {
        value = strtok(line, "\" \":");
        printf("\n%s", value);  
    }

    return 0;
}

This is the code I've written so far.

Solution

fscanf using scansets might work.

#include <stdio.h>
#include <stdlib.h>

int main ( void) {
    char *filename = "tempm.txt";
    char date[30] = "";
    char humidity[30] = "";
    FILE *fp = NULL;
    if ( NULL == ( fp = fopen ( filename, "r"))) {
        perror ( filename);
        exit ( EXIT_FAILURE);
    }
    fscanf ( fp, "%*[^0123456789]");//scan and discard up to first digit
    while ( 1 == fscanf ( fp, "%29[^\"]", date)) {//scan up to a quote
        fscanf ( fp, "%*[^0123456789]");//scan and discard up to next digit
        if ( 1 == fscanf ( fp, "%29[^\"]", humidity)) {//scan up to a quote
            printf ( "%s\n%s\n", date, humidity);
        }
        fscanf ( fp, "%*[^0123456789]");//scan and discard up to next digit
    }
    fclose ( fp);
    return 0;
}
