c简单排序字符串
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
void strsrt(char *str[], int num)
{
char *temp;
int top, seek;
for (top = 0; top < num - 1; top++)
{
for (seek = top + 1; seek < num; seek++)
{
if (strcmp(str[top], str[seek]) > 0)
{
//switch the value
temp = str[seek];
str[seek] = str[top];
str[top] = temp;
}
}
}
}
int main(void)
{
char *str[] = {
"test",
"hello",
"world",
"abc",
"hello two"
};
strsrt(str, 5);
int i = 0;
while (i < 5)
printf("%s\n", str[i++]);
return 0;
}
以上主要使用了strcmp()函数,实际上是排序了字符串指针而不是字符串,优点是保留了原始字符串的顺序
使用了最简单的算法,效率不是太高呵……
