Thread: Dynamic array size (Linked list ?)

Hello,

How can we create an array which size would grow as the user enter an input ? (Maybe linked lists ?)

Here is a piece of code that I have written where I have a fixed input, 128 characters long :

Code:

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

#define MAX_SIZE 128

int main(int argc, char **argv)
{
    printf("Input : ");
    char user_input[MAX_SIZE];
    fgets(user_input,MAX_SIZE,stdin);

    printf("You Wrote : \n");
    printf(" %s \n", user_input);
    
    const int ARRAY_SIZE = strlen(user_input);
    printf("%d characters found \n", ARRAY_SIZE);
    
    return 0;
}

By the way is this piece of code "safe" ?

Regards
