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

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;
}
