此作业:
char *pc1 = "test string";给我这个警告:
警告:不建议将字符串常量转换为'char *'
warning: deprecated conversion from string constant to 'char*'
这似乎还不错:
char *pc2 = (char*)("test string");这是一种更好的继续方法吗?
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*.
推荐答案字符串文字是C ++中的const char[],并且可能存储在只读内存中,因此如果您尝试修改它,程序将崩溃.将非const指针指向它是一个坏主意.
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.
