Answer 1

#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <sys/stat.h>

int main() {
    const char* filename = "d:\\data.txt";

    struct stat st;

    if (stat(filename, &st) == -1) {
        perror("stat");
        exit(EXIT_FAILURE);
    }

    printf("File size: %lu bytes\n", st.st_size);
    printf("Last change: %s", ctime(&st.st_ctime));
    printf("Last access: %s", ctime(&st.st_atime));
    printf("Last modification: %s", ctime(&st.st_mtime));

    return 0;
}
