C++ Program To Print Reverse A Sentence

Here, we will learn how to reverse any sentence in the C++ program.

Print Reverse A Sentence in C++ Language

This program takes a sentence from the user and reverses that sentence using recursion. This program does not use strings to reverse the sentence or store the sentence.

#include <iostream>
using namespace std;
// function prototype
void reverse(const string& a);
int main() {
 string str;
 cout << " Please enter a string " << endl;
 getline(cin, str);
 
 // function call
 reverse(str);
 return 0; 
}
// function definition
void reverse(const string& str) {
 // store the size of the string
 size_t numOfChars = str.size();
 if(numOfChars == 1) {
 cout << str << endl;
 }
 else {
 cout << str[numOfChars - 1];
 // function recursion
 reverse(str.substr(0, numOfChars - 1));
 }
}
