用C语言，输入n个字符串,n由键盘输出，将n个字符串中由小到大输出

Question

要求用指针。如char * str[5]
用选择法排序。

Answer 1

LZ说的是字符串排序吧~~

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

#define MAX 100

void main()
{
char *str[MAX], *tmp;
int n, i, j;

tmp = (char*)malloc(MAX * sizeof(char));
printf ("\nHow many strings: ");
scanf ("%d", &n);
getchar ();
printf ("input the strings: \n");
for (i = 0; i < n; i++) {
printf ("%2d: ", i + 1);
str[i] = (char*)malloc(MAX * sizeof(char));
scanf ("%s", str[i]);
for (j = 0; j < i; j++)
if (strcmp(str[i], str[j]) < 0) {
strcpy (tmp, str[j]);
strcpy (str[j], str[i]);
strcpy (str[i], tmp);
}
}
free (tmp);
printf ("\nThe strings are: \n");
for (i = 0; i < n; i++) {
printf ("%2d: %s", i + 1, str[i]);
free(str[i]);
}

}
