C Primer Plus （第6版）中文版 P288中程序清单11.11 scan_str.c程序，运行结果不对，麻烦各位，怎么修改才能运行正确

#include <stdio.h>
int main(void)
{
    char name1[11], name2[11];
    int count;

    printf("Please enter 2 names.\n");
    count = scanf_s("%5s  %10s", name1, name2);
    printf("I read the %d names %s and %s.\n", count, name1, name2);

    return 0;
}

Answer 1

count = scanf_s("%5s %10s", name1, name2);修改为：count = scanf_s("%s %s", name1, 11, name2, 11);

#include <stdio.h>
int main(void)
{
    char name1[11], name2[11];
    int count;

    printf("Please enter 2 names.\n");
    count = scanf_s("%s  %s", name1, 11, name2, 11); //
    printf("I read the %d names %s and %s.\n", count, name1, name2);

    return 0;
}
