C语言基础问题2 段错误（核心已储存）修改错误的经历

今天编写了一个程序是关于输出年与日的。要求输入数字月输出英文月，以下是最初的程序：

#include<stdio.h>

int main()

{
int year=0,month=0,day=0;
char str[]={"January","February","March","April","May","June","July","Auguest","September","October","November","December"};
printf("Please input follow this:\n" 
"month(1~31) day(1~12) year\n");
scanf("%d %d %d",&month,&day,&year);

printf("%d st %s %d\n",day,str[month-1],year);
return 0;

————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————

编译出现一堆错误，吓傻了。通过查看错误信息（很久没用指针数组了= =）



————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————

然后百度后找到这样的程序

#include<stdio.h>

int main()

{
char *s[]= {"Jan.","Feb.","Mar.","Apr.","May","June","July","Aug.","Setp.","Octo","Nove","Dec."};
char month;

printf("please input the month.\n");
scanf("%d",&month);
printf("\n%s\n",s[month-1]);
return 0;

}

发现要用指针数组初始化= =

但是改了之后可以编译了，但是输入今天的日期的时候问题来了= =继续段错误0.0



仔细看程序后发现时参数写错了= =。弄了两个多小时总算弄好了0.0

————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————

#include<stdio.h>

int main()

{
int year=0,month=0,day=0;
char *str[]={"January","February","March","April","May","June","July","Auguest","September","October","November","December"};
printf("Please input follow this:\n" 
"day(1~31) month(1~12) year\n");
scanf("%d %d %d",&day,&month,&year);

printf("%d st %s %d\n",day,str[month-1],year);
return 0;

}

/*程序最开始出现段错误（核心已转存的原因）：1、没有使用指针来初始化数组；

  2、将month与day的位置写反了，导致输入的时候碰巧输入了大于12的数字，
超过了指针数组初始化的范围*/
