居中添加名称的 sprintf 消息

转载作者：行者123 更新时间：2023-11-30 20:20:00

如果我仅使用Welcome消息，我的代码可以正常工作，但是当打印p->client_name指针时，消息不居中。

所以我的问题是如何将消息和客户端名称居中，就像它是一条消息一样。为什么它目前仅将消息欢迎居中

sprintf(message,"============================================================");
send_message(RED, message);
const char *mes = "Welcome";
sprintf(message, "[ %*s %s ]", (45 - strlen(message)) / 2 + ((strlen(message) % 2 == 0) ? 1 : 0) + strlen(message), mes, p->client_name);
send_message(RED, message);
sprintf(message,"============================================================");
send_message(RED, message);

示例:

=============================================
              [ Welcome Carol ]               
=============================================

原始问题解释的解决方案

这段代码看起来可以工作。注释解释了计算过程。测试代码展示了我如何测试这些东西。

/*
** Centre a pair of words in a given width without creating a single
** string to centre.
**
** Format will be "[ %*s %-*s ]"; what are the values required for the
** two lengths R1, R2 for a given width W and lengths L1, L2?

**      +----------------------------------------------------------+

**      +----------------------------------------------------------+
**
** W = G1 + L1 + 1 + L2 + G2
**
** G1 = G2 or G1 + 1 = G2
** L1 + L2 + 1 <= W (return G1 = G2 = 1 if it is bigger)
**
** For the purposes of the calculation, the leading "[ " and trailing " ]"
** are not counted as part of W.
**
** Total Padding T = W - (L1 + L2 + 1)
** Hence: G1 = T / 2
**        G2 = T - G1
**        R1 = L1 + G1
**        R2 = L2 + G2

请注意，代码不会尝试处理 L1 或 L2 为零的情况。在大多数情况下都可以这样做，除非非零长度太大。不过，这似乎没有必要。目标是将两个(非零长度)字符串居中。该计算也不会尝试处理字符串中的前导空格或尾随空格；简单地假设没有前导或尾随空格。它还假设一个单字节代码集；如果 UTF-8 包含 ASCII 范围之外的字符，它就无法正确居中(并且它也不会处理控制字符——退格、制表符、换行符、回车符等——明智地)。
