1. 解释错误消息"iso c++ forbids converting a string constant to char*"的含义 该错误消息表示,在ISO C++标准中,禁止将字符串常量(string constant)直接转换为char*类型的指针。字符串常量在内存中通常是存储在只读区域的,而char*类型的指针通常被用来指向可以修改的字符数组。因此,允许这种转换可能会导致未定义行...
const char* cp = strvar.c_str(); //MUCH safer. there isn't much you cannot do with string that you can do with char* and I strongly urge you to check out doing it as a string and asking if you can't see how to do it with that tool. ...

C++ std::stringstream to const char* conversion, The problem is that the string data your const char* points to has been freed after the return str;.The const char* pointer will stay valid as long as the associated std::string instance is within scope. This is assuming the code you have...

Stream<String> stringStream = testString.codePoints() .mapToObj(c -> String.valueOf((char) c)); 5. Conclusion In this quick tutorial, we learn to obtain a stream of Character from a String object by either calling codePoints() or chars() methods. This allows us to take full advantage...
voidreadImage(char*inputPath); 函数使用: readImage("C:\\xxxx\\girl.jpg"); 二、原因分析 在上面的方法中,方法的参数需要我们传递一个指针类型的字符。而我们在使用该方法的时候传递的确实一个常量。会导致常量强转为指针,因为会报这么一个警告。这个警告在有些编译器上就直接通不过了,有些编译器上可以通...
