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

int cmp(const void * a, const void * b)
{
    return strcmp(*(char **)a, *(char **)b);
}

int main(int argc, char* argv[])
{
    int n = 0;
    int i;
    printf("how many words?\n");
    scanf("%d", &n);
    char ** s = new char *[n];
    for (i = 0; i < n; i++)
    {
        s[i] = new char[100];
        scanf("%s", s[i]);
        char * t = s[i];
        while (*t != '\0')
        {
            if (t == s[i] && (*t >= 'a' && *t <= 'z')) *t = *t - 'a' + 'A';
            if (t > s[i] && (*t >= 'A' && *t <= 'Z')) *t = *t - 'A' + 'a';
            t++;
        }
    }
    qsort(s, n, sizeof(char *), cmp);
    for (i = 0; i < n; i++)
    {
        printf("%s\n", s[i]);
    }
    return 0;
}
