Feb 9, 2024 · In this article, we will learn how to reverse a string in C++. For Example, Input: myString = "Hello, GFG!" Output: myString = "!GFG ,olleH" Reverse a string in C++. Reversing a string means the last character should be the first character the second last should be the second and so on.
Jul 3, 2024 · 6 Different Ways to Reverse a String in C++. Table of Content. Reverse a String Using reverse () Function. Reverse a String Using Reverse Iterators. Reverse a String Using Loop. Reverse a String Using Two-Pointer Technique. Reverse a String Using Recursion. Reverse a String Using Stack. 1. Reverse a String Using reverse () Function.
Aug 3, 2022 · The built-in reverse function reverse() in C++ directly reverses a string. Given that both bidirectional begin and end iterators are passed as arguments. This function is defined in the algorithm header file.
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.
Jan 25, 2024 · Reverse String using a Loop: Initialize an empty string to store the reversed result. Iterate through the original string in reverse order. Append each character to the new string. The new string is the reversed version of the original string. Below is the implementation to reverse a string using loop in different programming languages:
Jul 17, 2023 · To reverse a string in C++ using a reverse_iterator, you can leverage the rbegin() and rend() member functions of std::string to iterate over the characters in reverse order. Here's an example:
Dec 23, 2023 · The standard way to reverse a string in C++ is to use the std::reverse algorithm from the <algorithm> header. This algorithm reverses the order of the elements in a range, such as a string or an array.
string::rbegin() and string::rend(), which stand for "reverse begin" and "reverse end" respectively, return reverse iterators into the string.
C++ String Reverse - To reverse a string in C++, you can use reverse() function of library header file or write a for loop that swaps the characters in place or copy the characters to char array in reverse order.
Sep 16, 2017 · using namespace std; int main() { ostringstream d; long long c = 123456789; d << c; //cout << c << endl; string str = d.str(); //cout << str.at(0) << endl; int size = str.size() - 1; //cout << size << endl; ostringstream e; e << str; string revStr = e.str(); for (int i = size; size==0; size--) { //cout << str.at(size); int j = 0;
