将字符串文字分配给 char*

这个作业:

char *pc1 = "test string";

给我这个警告:

警告:不推荐将字符串常量转换为 'char*'

warning: deprecated conversion from string constant to 'char*'

虽然这个看起来不错:

char *pc2 = (char*)("test string");

这是一种真正更好的方法吗?

Is this one a really better way to proceed?

注意:由于其他原因,我不能使用 const char*.

Notes: for other reasons I cannot use a const char*.

推荐答案

字符串字面量是 C++ 中的 const char[],可能存储在只读内存中,因此程序会崩溃如果您尝试修改它.将非常量指针指向它是个坏主意.

A string literal is a const char[] in C++, and may be stored in read-only memory so your program will crash if you try to modify it. Pointing a non-const pointer at it is a bad idea.
