Empty Output in Lowercase Program

[GonlyG]

I am given an ambiguous amount of text and must make all the letters lowercase. But my output is empty for no good reason.

#include <iostream>
#include <string>
#include <cctype>
#include <algorithm>
using namespace std;

int main() 
{    string test;
   for (int i=0; i<100;i++)
    {  
       getline(cin, test);
        test.erase(remove_if(test.begin(), test.end(), [](char ch) 
        { return ::isspace(ch) || ::ispunct(ch);}), test.end()); 
        transform(test.begin(), test.end(), test.begin(), ::tolower);
       cout<<test<<endl;
        }
        return 0;
}
