通常,在 C 或 C++ 中不可能简单地连接纯char *字符串,因为它们只是指向字符数组的指针。如果您打算在自己的代码中进行任何字符串操作,那么几乎没有理由在 C++ 中使用裸字符数组。 即使您需要访问 C 表示形式(例如,对于外部库),您也可以使用string::c_str(). Dan*_*dor 2 首先,没有任何东西null终止,而是...

Method 6 – Combining the CHAR and CONCAT Functions The CHAR function is useful to insert delimiters inside a join formula. In this example, we will combine CHAR and CONCAT functions to concatenate names. Steps: In cell E5 enter the following formula and press Enter: =CONCAT(C5,",",CHAR...
