How do you fix this error in C++ or how would you rewrite this code?

this is the error i am getting: Error2 error C2181: illegal else without matching if





this is me code:





#include %26lt;iostream%26gt;


using namespace std;





using std::cout;


using std::cin;


using std::endl;


int main()





{


//declare variables


int people = 1;


int fee = 0;


int totalpeople = 0;


int totalfee = 0;





while(people %26gt; 0)


{


cout %26lt;%26lt; "Enter number of registrants for this company (Enter 0 to exit): " %26lt;%26lt; endl;


cin %26gt;%26gt; people;





if(people %26gt;= 1 %26amp;%26amp; people %26lt;= 3)


{


fee = 150;


}


else if(people %26gt;= 4 %26amp;%26amp; people %26lt;= 9);


{


fee = 100;


}


else


{


fee = 90;


}


totalpeople += people;


totalfee += (people * fee);


}





cout %26lt;%26lt; "Total people attending: " %26lt;%26lt; totalpeople %26lt;%26lt; endl;


cout %26lt;%26lt; "Total fee collected: " %26lt;%26lt; totalfee %26lt;%26lt; endl;


cout %26lt;%26lt; "Average fee per person: " %26lt;%26lt; totalfee / totalpeople %26lt;%26lt; endl;





return 0;


}

Delete the semi-colon at the end of this line:


else if(people %26gt;= 4 %26amp;%26amp; people %26lt;= 9);


to take care of the compile error. Your logic is ok.





I doubt you need these lines:


using std::cout;


using std::cin;


using std::endl;





'using namespace std' should be all you need.
