while(n > 0){
printf("Give me a char:");
scanf(" %c",&cur->c);
cur->next = NULL;
printf("Give me a number:");
scanf("%d",&n);
if(n > 0)
{
cur->next = (letter*)malloc(sizeof(letter));
cur=cur->next;
}
}
应该只接受字母字符,EditText
只接受单个字(空格字符也不允许)
答案 0 :(得分:0)
在xml:
中的edittext中添加此属性# handle trailing slashes (if not a directory)
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)/$ $1 [R,L]
# rewrite rule that internally adds the .html extension
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME}.html -f
RewriteCond %{REQUEST_FILENAME} !^.+\.html$
RewriteRule ^(.+[^/])$ $1.html
并在editText上添加一个过滤器来管理双重空间删除问题:
android:digits="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"
