Question

#include <iostream>
#include<string>
using namespace std;
int main(){
string s;
string s1;
cin>>s;
for(int i=s.size()-1;i>=0;--i){

Answer 1

#include <iostream>
#include<string>
using namespace std;
int main(){
string s;
string s1;
getline(cin,s);
for(int i=s.size()-1;i>=0;--i){
s1+=s[i];
}

cout<<s1;

return 0;
}

It work now...

Answer 2

Getline function which is in string header...
It allows accepting and reading single and multiple line strings from the input stream. In C++, the cin object also allows input from the user, but not multi-word or multi-line input.

Answer 3

cin stops when it encounters a blank space. That is why you only get one word.

getline accepts the blank spaces as part of the string and stops at the end of the line('\n'). or when you hit the enter key.
