Question

用C++输入一个大写字母，输出字母表中它前面和后面的字母。如果输入的字母为A或Z，（接下）哪里错了

#includemain(){ char a; a=getchar(); scanf("%d",&a); { if(a<'a'||a>'Z') printf("you data is error\n"); if(a>'A'&&a<'Z') printf("%c,%c\n",a-1,a+1); if(a=='A') printf("ûÓÐÇ°Ãæ×Öĸ,%c",a+1); if(a=='Z') printf("ûÓкóÃæ×Öĸ,%c",a-1); }

Answer 1

#include "stdio.h"
main(){
char a;
a=getchar();
if(a<'A'||a>'Z')
printf("you data is error\n");
if(a>'A'&&a<'Z') printf("%c,%c\n",a-1,a+1);
if(a=='A') printf("它的后一个大写字母,%c",a+1);
if(a=='Z') printf("它的前一个大写字母,%c",a-1);
}
