C++ | Syntax Error: Identifier 'i' -

hey guys, i'm pretty sure else has had problem too, couldn't find related problems. stupid typo or something, i'm not able figure out >.<

what's wrong code, error:

error c2061: syntax error : identifier 'i'

#include <iostream> #include <string> using namespace std;  class mahinluokka {     public:         void setnum(int);         int getnum();     private:         int mahi_num; };  int main() {     int i;     {         cout << "insert number between 1-100" << endl;         cin >> i;     } while > 100 || < 0;     mahinluokka mahi;     mahi.setnum(i);     cout << mahi.getnum() << endl;     mahi.setnum(5);     cout << "mahi_num set 5" << endl;     cout << mahi.getnum() << endl;      // end     int x;     cin >> x;     return 0; }  void mahinluokka::setnum(int number) {     mahi_num = number; }  int mahinluokka::getnum() {     return mahi_num; } 

you need enclose conditions in parentheses. in other words, change this:

} while > 100 || < 0; 

to this:

} while(i > 100 || < 0);
