C++ questions need help~!!

For a question needs me to print the last line of each paragraph, For example, here is the para. txt:

-------------------------------------------------------------------------------------

(should notice there are blanks between each paragraph. )

-----------------------------------------------------------------

And this is the starter code:

------------------------------------------------------------------

#include

#include

int main() {

std::string line, prevLine;

// Read & process line-by-line until EOF

while (std::getline(std::cin, line)) {

// Print the line

std::cout endl;

}

return 0;

}

------------------------------------------------------

Please think about how to add suitable if-statement(s) to check and print the last line of each paragraph in "para.txt" . Note: The std::string::empty() method will come in handy here.
