In C Programming, a string doesn't have a specific return type as it's essentially an array of characters. So, if a function is returning a string, it should be declared to return a pointer to a char (char*), since a string in C is represented as an array of characters terminated by a null character ('\0').

Why to use String in c?
C doesn't have String data-type, so don't use it.
How do you get value of a string in reverse order in c?
Assume C#, not C: Traditional way: public string Reverse(string s) { if (string.IsNullOrEmpty(s)) return s; // "" or null char[] characters = s.ToCharArray(); Array.Reverse(characters); return new string(characters); } or as an extension method: public static string Reverse(this string s) { if (s == "") return ""; char[] characters = s.ToCharArray(); Array.Reverse(characters); return new string(characters); } The differences of the 2 methods above is on the caller (how to use Reverse()), and they may co-exist: For example: string test = "abc"; string result1 = Reverse(test); // traditional way string result2 = test.Reverse(); // call the extension
What is the difference between a C plus plus string and a C-style string?
A std::string is an object that encapsulates an array of type char whereas a C-style string is a primitive array with no members. A std::string is guaranteed to be null-terminated but a C-style string is not.
What is the default return type in C and C plus plus?
No. There is no default return type for functions, it must be explicitly specified in both the function declaration and in the definition. To specify no return value, return void. To return a variant type, return void* (pointer to void). Otherwise return the exact type.
C plus plus program to count digit in a string?
Use the following function to count the number of digits in a string. size_t count_digits (const std::string& str) { size_t count = 0; for (std::string::const_iterator it=str.begin(); it!=str.end(); ++it) { const char& c = *it; if (c>='0' && c<='9'); ++count; } return count; }

How do you return a word in a string so that every letter is a symbol eg egg must be 3 symbols?
Not really sure what you mean by symbol. I will assume that you are talking about a character Here is a method that will seperate each char of a String in an array of char public char[] seperateChar(String s) { char [] c = new char[s.length]; for(int i = 0; i < s.length(); i++) { c[i] = s.charAt(i); } return c }
What does 'strtok' mean in computing?
A strtok is used as a search string in computing where it can find a variable that is typed after " " (add a space), and then return it as a string. It is part of the C++ programming technique.
Why the return type of all the function by default is int in c?
Because int is the most common data-type in C. Don't rely on this though, always specify the return type explicitly.
