编一程序，输入月份号，输出该月的英文月名。例如，输入“3”，

	#include<stdio.h>



	int main()



	{char *month_name[13]={"illegal month","January","February","March","April",



	"May","June","july","August","September","October","November","December"};



	int n:



	printf("input month:\n”)；



	scanf("%d",&n)；



	if((n<=12)&&(n>=1))



	printf("It is %s.\n",*(month_name+n))；



	else



	printf（"It is wrong.\n")；



	return 0；



	}
