Open the text file and read the content line by line and put into array

Hi
I am writing the c code to open text file, read the line and break the string if there is a white space and put them into two different arrays.

But I want to know how to detect the blank line and skip to another line and do the same thing. Below is my code. Attached is the text file that I want to get the data from

Code:

---

void main(void)
{
    char buffer[1000] ; 
    char *line; 
    char *token;
    char *breaks = "  ";
   
   
    FILE *fstream = fopen("try1.txt","r"); 
    if(fstream == NULL) 
    {     
      printf("\n file opening failed ");     
    }
   
   
    do
    {
      line=fgets(buffer, 100000, fstream);
      printf("\nline = %s", line);
     
    /*  token = strtok(line, breaks);
      while(token != NULL)
      {
        printf("\ntoken = %s", token);
        token = strtok(NULL, breaks);
      } */
     
      token = strtok(line, breaks);
      printf("\ntoken = %s", token);
     
      token = strtok(NULL, breaks);
      printf("\ntoken = %s", token);
     
      token = strtok(NULL, breaks);
      //printf("\ntoken = %s", token);
     
    }
    while (line != NULL);
   
    fclose(fstream);
 
}

Be consistent with your indentation.

Don't put newlines BEFORE the strings you are printing. That is bizarre. Normally we put them after.

Code:

---

// Don't forget the header files.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

// main should be declared to return an int
int main(void) {
    // A separate "buffer" string and "line" pointer are not needed.
    char line[1000];
    char *token;
    // Don't use actual tabs in a string. Use \t instead.
    // You also need \n since fgets leaves it at the end of the string.
    const char *breaks = " \t\n";  // and it should be const since it's pointing to a string literal

    FILE *fstream = fopen("try1.txt", "r");
    if (fstream == NULL) {
        // perror prints the reason for the failure
        perror("fopen");
        // If the file doesn't open, you should exit.
        exit(EXIT_FAILURE);
    }

    // Don't put a random line size here, especially if it's greater than the actual string.
    // Usually we use the actual string length.
    // And testing if the fgets return value is NULL at the end of the loop is too late since
    // you've already tried to get tokens from it with strtok. So test it here.
    while (fgets(line, sizeof line, fstream) != NULL) {
//        printf("line = %s", line);
        token = strtok(line, breaks);
        if (token != NULL) { // skip empty lines
            printf("token = %s\n", token);
            token = strtok(NULL, breaks);
            printf("token = %s\n\n", token);
        }

        // Why would you do this a third time if there's
        // only two tokens on the line?
//        token = strtok(NULL, breaks);
    }

    fclose(fstream);

    // You should explicitly return 0 at the end of main to indicate successful completion.
    return 0;
}

Thanks for you explanation and code. If I follow the same the program will also print the empty token as shown below. But I dont want to print that. How can I change the code?


token = 0012E02B00
token = 0F80

token = 0012DA2398
token = 8

token = 0012E02B00
token = 0F80

token = 0012DA2398
token = 8

token =
token =<?>
