hello!

im new to c++ (and to this forum). i've been struggling with this hw assignment for days now and still cant seem to get it right.

i attached my assignment.

what i cannot seem to get right is how to make the program exit without having it ask me again to enter my two values and then exit.Code:#include <iostream> #include <iomanip> using namespace std; int main () { const int exit_out= 9; int n1, n2, result, selc; char sign; result=0; cout<<"Enter one of the following values:"<<endl; cout<<setw(10)<<left<<"1"<<"Add two numbers"<<endl; cout<<setw(10)<<left<<"2"<<"Subtract two numbers"<<endl; cout<<setw(10)<<left<<"3"<<"Multiply two numbers"<<endl; cout<<setw(10)<<left<<"4"<<"Find the modulus of dividing two numbers"<<endl; cout<<setw(10)<<left<<"9"<<"Quit program"<<endl<<endl; cout<<setw(4)<<left<<" "<<"Enter selection now: "; cin>> selc; cout<<endl; do { cout<<"Enter the first number: "; cin>>n1; cout<<"Enter the second number: "; cin>>n2; switch (selc) { case 1: result= n1+n2; sign='+'; break; case 2: result= n1-n2; sign= '-'; break; case 3: result=n1*n2; sign= '*'; break; case 4: result=n1%n2; sign= '%'; break; default: cout<<"Invalid selection, please try again."<<endl; break; } cout<<"The result of "<<n1<<sign<<n2<<" is "<<result<<endl<<endl; cout<<"Enter one of the following values:"<<endl; cout<<setw(10)<<left<<"1"<<"Add two numbers"<<endl; cout<<setw(10)<<left<<"2"<<"Subtract two numbers"<<endl; cout<<setw(10)<<left<<"3"<<"Multiply two numbers"<<endl; cout<<setw(10)<<left<<"4"<<"Find the modulus of dividing two numbers"<<endl; cout<<setw(10)<<left<<"9"<<"Quit program"<<endl<<endl; cout<<setw(4)<<left<<" "<<"Enter selection now: "; cin>> selc; cout<<endl; cout<<"Enter the first number: "; cin>>n1; cout<<"Enter the second number: "; cin>>n2; } while (selc != exit_out); return 0; }

in the switch function, the default does show up right, but it attempts to continue asking for more values and tries to give a result, when i do not want it to.

thanks for any help
