I want to read a formating hour ( HH:MM:SS) from a text file in c and pass every number until to fine ':' to three ints : h , m, s

How can be possible?

I wrote the code to pass the string to a char but i don't know if that's the best option.

/* Source Code to read a text of string from a file. */

#include <stdio.h>
#include <stdlib.h> /* For exit() function */
int main()
{
	
   char c[1000];
   FILE *input;
   if ((input = fopen("time.in","r"))==NULL){
       printf("Error! opening file");
       exit(1);         /* Program exits if file pointer returns NULL. */
   }
   
   fscanf(input,"%[^\n]",c);
   printf("Data from file:\n%s",c);
   fclose(input);
   
   
   
   return 0;
}
