在C++中, char* p = "abc"; // valid in C, invalid in C++ 会跳出警告:warning: ISO C++ forbids converting a string constant to 'char*' [-Wwrite-strings] 改成下面会通过warning char* p = (char*)"abc"; // OK 或者改成下面: char const *p = "abc"; // OK…

第1种字符串赋值方式: char * fileName="./2017-09-02-10-34-10.xml";//这一种字符串赋值方式已经被ISO禁止了 第2种字符串赋值方式: char str[] ="./2017-09-02-10-34-10.xml"; char *fileName=str; 第3种字符串赋值方式: char fileName[] ={"./2017-09-02-10-34-10.xml"};//有无大括号都可以 warn…
