February 3, 2023

Reverse String :

String is defined as the sequence of characters . Reverse string in C++ is printing the character from end to start

How to reverse a String in C++ :

In general, String can be reversed in C++ by using loop or also there is inbuilt method.

Below are the two techniques to reverse the string in C++ :

Method 1 :

#include<iostream>
using namespace std;

int main() {
    string str = "atsniperP";
    int len = str.length();
    cout< <"The reverse string is : ";
    for(int i=0;i < len;i++){
        cout< < str[len-i-1];
    }
    return 0;
}

Output :

The reverse string is : Prepinsta

In the above program, we traverse the string using for loop and print the particular character of the string to get the reverse string.

Method 2:

Run

#include<iostream>
#include<bits/stdc++.h>
using namespace std;

int main() {
    string str = "atsniperP";
    
    reverse(str.begin(), str.end());
    cout<<"The reverse string is : "< < str;
    
    return 0;
}

Output :

The reverse string is : Prepinsta

In the above program, we use the inbuilt method reverse to reverse the string.
