Why for "The Spy Life" this code doesn't work with ASCII code :

Question

#include <iostream>
#include <string>
using namespace std;
int main() {
string s;
cin>>s;
int n;
n=s.size();
for(int i=n-1;i>=0;i--){
if((s[i]<91 && s[i]>64) || (s[i]>96 && s[i]<123) || s[i]==' '){
cout<<s[i];
}
}
return 0;
}

Answer 1

cin>>s; by this, cin accept only single word. You need read entire line of string contains more words also..
Use getline method...
getline(cin, s);
