int main()
{
    char p[25];

    printf("Hello world!\n");
    scanf("%s",p);

    printf("%s\n",p);


    return 0;
}

Or

#include <stdio.h>
#include <stdlib.h>

int main()
{
    char *p=NULL;

    p=malloc(10);

    printf("Hello world!\n");
    scanf("%s",p);

    printf("%s\n",p);


    return 0;
}

Or

#include <stdio.h>
#include <stdlib.h>

int main()
{
    char *p=NULL;

    p=malloc(10);

    printf("Hello world!\n");
    gets(p);

    printf("%s\n",p);


    return 0;
}

It's somewhat amusing how you managed to pick the two worst possible options. gets() is completely unsafe, and the latest C standard actually removed it from the library. scanf()'s "%s" specifier without a field width is no better than gets(). In both cases input longer than the memory can hold will cause buffer overflow. They also do different things in that gets() reads a whole line while scanf("%s"...) only reads up to the nearest whitespace.

The recommended go to solution is fgets():

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

int main(void)
{
    char buf[BUFSIZ];

    printf("Enter a string: ");
    fflush(stdout);

    if (fgets(buf, sizeof buf, stdin)) {
        buf[strcspn(buf, "\n")] = '\0'; // Optionally remove any newline character
        printf("'%s'\n", buf);
    }

    return 0;
}
