从键盘输入一个数字n，从1月~n月将英文月份按字母顺序排序并输出。

若n不合法，输出“Illegal”

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

void sort(char month[][10], int n)
{
	int i, j;
	char temp[10];
	for (i = 0; i < n; i++)
		for (j = 0; j < n - i - 1; j++)
			if (strcmp(month[j], month[j + 1]) > 0)
			{
				strcpy(temp, month[j]);
				strcpy(month[j], month[j + 1]);
				strcpy(month[j + 1], temp);
			}
}
int main()
{
	char month[12][10] = { "January","February","March","April","May","June","July","August","September","October","November","December" };
	int n, i;
	scanf("%d", &n);
	if (n < 1 || n > 12)
	{
		printf("Illegal");
		return 0;
	}
	else
	{
		sort(month, n);
		for (i = 0; i < n; i++)
		{
			printf("%s\n", month[i]);
		}
	}
	return 0;
}
