在C / C C-字符串定义++ [英] C-string definition in C / C++

问题描述

真的词C字符串，在C / C的意思++？字符指针？字符数组？或字符常量可能指针/常量数组？

What really means by word "C-string" in C / C++? Pointer to char? Array of characters? Or maybe const-pointer / const array of characters?

推荐答案

一个C字符串是用0（空字符）字节结束的字符数组。该数组，而不是任何指针，是的字符串的。因此，C字符串的任何终端子阵也是一个C字符串。类型的指针的char * （或为const char * 等）通常被认为是指向字符串，但他们实际上会指向一个字符串的元素，通常作为指针的初始的字符串的元素处理。

A "C string" is an array of characters that ends with a 0 (null character) byte. The array, not any pointer, is the string. Thus, any terminal subarray of a C string is also a C string. Pointers of type char * (or const char *, etc.) are often thought of as pointers to strings, but they're actually pointers to an element of a string, usually treated as a pointer to the initial element of a string.
