The c_str() function is used to return a pointer to an array that contains a null terminated sequence of character representing the current value of the string. We are giving 5*10=50memory locations for the array elements to be stored in the array. The arraySize must be an integer constant greater than zero and type can be any valid C data type. and FYI the 4-Bytes was referring to how many bytes I hard coded the section to process, remember thi. Using static array: Lifetime of a static variable is throughout the program. Typically, returning a whole array to a function call is not possible. Array objects also implement the buffer interface, and may be used wherever bytes-like objects are supported. The problem is, we return address of a local variable which is not advised as local variables may not exist in memory after function call is over.So in simple words, Functions can’t return arrays in C. However, inorder to return the array in C by a function, one of the below alternatives can be used. The type of both the variables is a pointer to char or (char*), so you can pass either of them to a function whose formal argument accepts an array of characters or a character pointer. C and C++ programming languages provide the strlen() function in order to calculate or return the size of the given string or char array. array.append (x) ¶ Return char[]/string from a function, Im fairly new to coding in C and currently im trying to create a function that returns a c string/char array and assigning to a variable. In anycase, I understand why you might want to use a char array, but seriously, use string, or vector it is C++, not C. The overhead is tiny for any modern computer. Make sure that the size you put inside [] is large enough to hold all the characters in the string, plus the terminating NULL character. std::tuple, std::pair | Returning multiple values from a function using Tuple and Pair in C++.
