The use of the reverse string in C program is used to reverse the letters in the string. An example would be reverse me would be reversed to em esrever.
To reverse a number, first convert the number to a string, then reverse the string. Given your number consists of alphanumeric characters, the number must already be a string so simply reverse the string: #include<string> using std::string; string reverse (const string& s) { string str {}; for (auto c : s) str.insert (str.begin(), c); return str; } int main () { std::cout << "Enter a number: "; string s {}; std::cin >> s; std::cout << "The number in reverse is: " << reverse (s); }

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

There are five common methods of string inversion in Python: using string slicing, using recursion, using the list reverse () method, using stack and using for loop. Use string slicing (most concise) s = "hello" reversed_ s = s[::-1] print(reversed_s) >>> olleh Use recursive def reverse_ it(string): if len(string)==0: return string else: return reverse_ it(string[1:]) + string[0] print "added " + string[0] string1 = "the crazy programmer" string2 = reverse_ it(string1) print "original = " + string1 print "reversed = " + string2 Use the list reverse() method in [25]: l = ['a', 'B', 'C','d '] ...: l.reverse() ...: print (l) ['d', 'c', 'b', 'a'] Using stack def Rev_ string(a_string): L = list (a_string) # simulate all stacking new_ string = "" while len(l)>0: new_ String + = l.pop() # simulate stack out return new_ string Use the for loop #for loop def func(s): r = "" max_ index = len(s) - 1 for index,value in enumerate(s): r += s[max_index-index] return r r = func(s) The above are the five common methods of string inversion in Python. I hope it can be helpful to your learning of Python strings
Console.WriteLine("Please input a string:"); string str = Console.ReadLine(); Console.WriteLine("Number of characters: " + str.Length);
The printf() function prints a formatted string.
The following codes only applied to unsigned integers: public int Reverse(int inputNumber) { string inputString = inputNumber.ToString(); string reversed = StringUtil.Reverse(inputString); return int.Parse(reversed); } public class StringUtil { // returns a reversed string from the given one public static string Reserve(string originalString) { StringBuilder sb = new StringBuilder(); char[] charArray = originalString.ToCharArray(); for (int i = charArray.Length - 1; i >= 0; i--) { sb.Append(charArray[i]); } return sb.ToString(); } }
