C++ String to Char Array To convert a string to character array in C++, you can directly assign the string to character array, or iterate over the characters of string and assign the characters to the char array, or use strcpy() and c_str() functions. We shall go through each of these...
In this article, we will be focusing on the different ways to convert String to char array and char array to String in C++. While dealing with String data, we may need to convert the string data items to character array and vice-versa. This tutorial will help you solve exactly that. Co...
