Mar 19, 2025 · C++ STL provides the std::reverse() method that reverses the order of elements in the given range. We can use this function to reverse the string by passing the iterators to the beginning and the end of the string.

Apr 23, 2025 · In C++, we can reverse a string in various different ways as show below: C++ STL provides a built-in function reverse (), which can be used to reverse the string efficiently. Example. Time Complexity: O (n), where n is the length of string.

Jan 29, 2025 · // C++ program to reverse a string using backward traversal #include <iostream> #include <string> using namespace std; string reverseString (string & s) {string res; // Traverse on s in backward direction // and add each charecter to a new string for (int i = s. size ()-1; i >= 0; i--) {res += s [i];} return res;} int main {string s = "abdcfe ...

Apr 21, 2025 · Let us see how we can use the strrev() function in C++ to reverse strings. cout<<"\n"<<str; return 0; } Output: The code above illustrates the working of the function strrev() very well. For a string ‘str’, the function reverses it successfully as we can see in the output itself.

Here is a C++ program to reverse a string using for loop, while loop, recursion and inbuilt reverse function with detailed explanation and examples.

Oct 13, 2008 · std::string reverse_string(std::string &str) { const char*buf = str.c_str(); char *start = const_cast<char*>(buf); char *end = start + strlen(buf) - 1; char t; while(start < end) { t = *start; *start = *end; *end = t; start ++; end --; } str = buf; return str; }

Feb 5, 2025 · Learn multiple methods for reversing a string in C++, from basic manual approaches (like loops, recursion, stacks) to using STL (Standard Template Library) functions, and compare their performance. In programming, string reversal involves flipping the order of characters to achieve a reversed output.

Summary: In this tutorial, we will learn different ways to reverse a string in C++ programming language. Example: Output: edoc. reverse() method available in the algorithm header file can reverse a string in-place without writing any boilerplate code. All we need to do is to pass the begin and end iterator as arguments to the particular method.

Want to Program to Reverse a String in C++, learn how to code a C++ program to print the given string in reverse order along with its algorithm and explanation.

Jun 5, 2023 · In this article, we explored several approaches to reverse a string in C++. We covered three main techniques: using the library's std::reverse function, employing the two-pointer technique, and leveraging recursion.
