当我们使用char pointer[] = "hello"时,它会被存储到读写区中.而当我们使用charpointer = "hello"时,"hello"会被存储到只读区,而pointer这个指针会被存储到读写区.所以,我们使用指针修改只读区的时候,因为是undefined operation,所以会出现Segment Fault*的异常....
回答：这里的 pointer 指向的是一个字符串,字符串的首地址赋给 pointer printf("%s\n",pointer); //输出Hello World!// printf 遇到指向字符串的指 //针时,输出字符串(就是这样定义的) printf("%s\n",*pointer); //输出H printf("%d\n",pointer); //输出pointer指向的地址
“不兼容的指针类型将“string *”(又名“char **”)传递给“const char *”类型的参数;使用 * [-werror,-wincompatible-pointer-types] 取消引用”错误是C++编译器的一个警告。这个错误通常是因为你试图将一个指向字符串的指针传递给需要一个指向常量字符的函数。为了解决这个问题,你只需要在声明指向字符串的...
it represents a 16-bit wide character used to store Unicode encoded as UTF-16LE, the native character type on Windows operating systems. The wide character versions of the Universal C Runtime (UCRT) library functions usewchar_tand its pointer and array types as parameters and return values, ...
And it that case, isn't a c++ string almost the same as a c string. (A char array but one is always null terminated and have some special functions). So if I provide the strcpy with a pointer to the first char(location) of c++ str, woudln't that be the same as providing it ...
For example,signed int,unsigned int,short int,long int, etc. are all valid data types in the C language. long long num = 123456789987654321; // we cannot store a value this big value using int data type. Now let's see the range for different data types formed as a result of the 5...

The std::strtol function converts a C-style string (char array) to a long integer. It allows you to specify the base of the numeral system (e.g., decimal, octal, hexadecimal) and provides a pointer to the first invalid character encountered during parsing. It’s part of the C standard...
