How to create struct of every word in .txt file in C?

if given a short .txt file that contained the following content, how would you go about creating a struct for every word in a specific line in the file and determining if it had an * before it

Sample File:

a *b c 
*d e f

I have created this structs:

typedef struct Unit
{
    bool hasStar;
    char variable[1];
} unit;

So I would want to create a struct for a, *b, and c for example. I'm not sure how to do this, so any help on how best to approach this would be amazing

Solution

Firstly, you have to change char variable[1] to char varibale[3] at least for storing the string "*a" for example.

You can get line by line from the file using fgets then using strtok to separate the line by space character.

FILE *fp = fopen("intput.txt", "r");
if(!fp)
  // handle error.
char line[256];
while(fgets(line, sizeof(line), fp) {
    // using strtok to split each line
}

For spliting the line using strtok and verify the star symbol * at the begin of word:

char * token = strtok(line, " ");
while (token != NULL) {
    strcpy(units[i].variable, token);
    if (token[0] == '*')
       units[i].hasStar = true;
    else
        units[i].hasStar = false;
    strtok(NULL, " ");
    i++;
}

Before while loop of fgets, you have to declare the size of units and initialize i first, for example the code below, i initialize the size of array units that is eaqual to 100:

unit units[100];
int i = 0;
