Please help me understand the problem with my code. I will add the else statements later. Here is the long list of my errors:

soccer.cpp: In function 'int main()':

soccer.cpp:22:6: error: no match for 'operator' (operand types are 'std::istream' {aka 'std::basic_istream'} and 'std::__cxx11::string' {aka 'std::__cxx11::basic_string'})
