![]() ![]() Disadvantages of C-stringsĬ arrays do not track their own size. These standard C-string functions require the strings to be terminated with a null character to function correctly. These functions are defined in the C header string.h and in the C++ header cstring. The standard library contains functions for processing C-strings, such as strlen, strcpy, and strcat. The null character is automatically appended at the end for your convenience. String literals are indicated by using the double quote ( ") and are stored as a constant ( const) C-string. This last part of the definition is important: all C-strings are char arrays, but not all char arrays are c-strings.Ĭ-strings of this form are called “ string literals“: const char * str = "This is a string literal. C-strings are simply implemented as a char array which is terminated by a null character (aka 0). Neither C or C++ have a default built-in string type. Let’s start off with a review of built-in string support, henceforth referred to as “C-style strings”. ![]() Built-in String Support (C-style Strings) Let’s start off by reviewing built-in string support in C/C++. std::string provides much more straightforward string management interfaces, allows you to utilize SBRM design patterns, and helps eliminate string management overhead. Today we’ll continue our C-to- C++ migration theme by focusing on std::string, a container-like class used to manage strings. ![]()
