void printchars()
{
for (x=128;x<224;x++)
write(x);
我希望X能成为书写功能的char子。 如何改变拟由书写功能作为果园处理的x,但 lo中的 in子?

What is the point of making x
an int
if you re just going to strip away its range? That s what makes this a very strange request. You should just make x
a unsigned char
-- for(unsigned char x = 128; x <224; ++ x) { ...
.
如果你只是想确保你重新打上<代码>unsign char/code> model specialized of write<>
,那么就这样说:
write<unsign char>x;
否则,你就不得不使用打字方式:
<代码>write((未签名)x);
int
或。 我对此作了解释。 <代码>char
有一系列-128至+127。 <代码>unsign char, 范围为0-255。
Cast x to a char:
write(static_cast<char>(x));
请注意,X要成为char子也是 counter。
