I’m trying to get all lines with the word time in it. How do I make this work? The only thing it does right now is to find the word “time”, but only one, and fgets does nothing with the line for me.

grep works well:
grep time file.txt
but I need to do everything in C.

Code:

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


#define MAX 15
#define FIND "time"

char fileText[14];

int main() {

FILE *fptr, *fptw;
  fptr=fopen("file.txt","r");

  fseek(fptr, 0, SEEK_END);
  long pos = ftell(fptr); 
  fseek(fptr, 0, SEEK_SET);

  char *arr = malloc(pos + 1);
  fread(arr, pos, 1, fptr);
  arr[pos] = '\0'; 


    if (strstr(arr, FIND) != 0){
        fgets(fileText, MAX, fptr); 

        printf("found\n");
        printf("%s\n\n",fileText); }
   else{
       printf("Not found\n"); }

   free(arr);

  return 0;
}
