我有以下字母数组
$_CharCodes = array(
"A" => 01, "B" => 02, "C" => 03, "D" => 04, "E" => 05, "F" => 06,
"G" => 07, "H" => 08, "I" => 09, "J" => 10, "K" => 11, "L" => 12,
"M" => 13, "N" => 14, "O" => 15, "P" => 16, "Q" => 17, "R" => 18,
"S" => 19, "T" => 20, "U" => 21, "V" => 22, "W" => 23, "X" => 24,
"Y" => 25, "Z" …我需要以下帮助:根据索引初始化为0,$ test小于26,索引增加1的条件创建for循环.对于每次迭代,打印字母表的当前字母.从字母A开始.因此,对于每次迭代,在单独的行上打印单个字母.每次循环运行时我都无法递增char
for ($test = 0; $test -lt 26; $test++)
{
[char]65
}
我试过多次尝试将char 65到90递增但没有成功.是否有更简单的方法来增加字母表以显示运行的每个循环的字母？
我想创建一个函数来决定字符是Haskell中字母表中的字母
isLetter :: Char -> Bool
因此结果可能如下所示:如果我输入isLetter 'c',结果将是True,如果是isLetter ' ',那么结果就是False.
我觉得标题说的够多了。
void onClickSubmit(char submit)
{
if(submit.//check if it is alphabetical)
{
//some code
}
}
我如何检查字符提交是否在字母表中？
