Compile issues when using STD List Library

I have been given the following code as an example to try and compile. Unfortunately I am having issues with it.

#include <list>
#include <iostream>
using namespace std;

int main(int argv, char* argc[])
{
    int i;
    list<int> 1;
    do {
        cin >> i;
        1.push_back(i);
    } while (i!=0);

    1.sort();

    list<int>::const_iterator iter;
    for(iter=1.begin();iter!=1.end();iter++)
            cout << (*iter) << endl;

    return 0;
}

First I tried the code in eclipse using Linux GCC but I get the following errors:

list.cpp:18:3: error: invalid suffix "push_back" on floating constant
   1.push_back(i);
   ^
list.cpp:21:2: error: invalid suffix "sort" on floating constant
  1.sort();
  ^
list.cpp:24:11: error: invalid suffix "begin" on floating constant
  for(iter=1.begin();iter!=1.end();iter++)
           ^
list.cpp:24:27: error: exponent has no digits
  for(iter=1.begin();iter!=1.end();iter++)
                           ^
list.cpp: In function ‘int main(int, char**)’:
list.cpp:15:12: error: expected unqualified-id before numeric constant
  list<int> 1;

Changing the language to c++11 I get the following errors:

list.cpp:24:27: error: exponent has no digits
  for(iter=1.begin();iter!=1.end();iter++)
                           ^
list.cpp: In function ‘int main(int, char**)’:
list.cpp:15:12: error: expected unqualified-id before numeric constant
  list<int> 1;
            ^
list.cpp:18:3: error: unable to find numeric literal operator ‘operator""push_back’
   1.push_back(i);
   ^
list.cpp:21:2: error: unable to find numeric literal operator ‘operator""sort’
  1.sort();
  ^
list.cpp:24:11: error: unable to find numeric literal operator ‘operator""begin’
  for(iter=1.begin();iter!=1.end();iter++)

Is anyone able to shed some light on what is going wrong?
