read a line with getchar

[kalar]

I want to read a line and put each word of this line in a linked list but i must use getchar.My problem is on how to read a line with getchar.(forget linked lists)
i make this

#include <stdio.h>

#define len 64

int main(void){
    
    char str[len];
    int i;
    
      do{
         i=0;
         str[i]=getchar();
         i++;
         }while (str[i-1]!= '\n' && i<len);
         
     str[i-1]='\0';

     printf("%s", str); 

     return 0;
          }

The problem the printf str doesn't print anything

You set i=0 every time the loop executes. i never exceeds one. Then you set str[0] to '\0'. Set i=0 outside the loop.

Ok. Now i want to seperate the words.
example if i give:
hello world

I want to take hello and add it into the list and then for world do the same thing
I thought something like this: in a for loop if i find any ' ' character i will replace it with \0. Will this work? or any other idea to do this?
