Why doesnt getline() work with files?

Question

I tried
#include <fstream>
#include <string>
ifstream Myfile("file.txt");
int temp;. //to get and store file values temporarily
while(Myfile) {
getline (Myfile, temp, ' , '); // to delimit CSV
}
How can I fix this?

What exactly happened when you executed it? (Btw. the playground doesn't support file interaction as far I know)
