while(complete==0)
{
int input;
int firstno;
int secondno;
int result;
cout<<"\n\t\t Enter the first NO:";
cin>>firstno;
cout<<"\n\t\t Enter the srcond No:";
cin>>secondno;
 
cout<<"\n\t\t\t\t for(+) Enter 1";
cout<<"\n\t\t\t\t for(-) Enter 2";
cout<<"\n\t\t\t\t for(*) Enter 3";
cout<<"\n\t\t\t\t for(\) Enter 4";
cout<<"\n seliction";
cin>>input;
switch (input) {
case 1:   //Note the colon,not a semicolon
{
result=firstno+secondno;
cout<<"\n\t\t\t the result:"<<result;
break;
}
case 2:  //Note the colon,not a semicolon
{
result=firstno-secondno;
cout<<"\n\t\t\t the result"<<result;
break;
}
case 3:  //note the colon,not a semicolon
{
result=firstno*secondno;
cout<<"\n\t\t\t the result:"<<result;
break;
}
case 4:  //note the colon,not a semicolon
{
result=firstno/secondno;
cout<<"\n\t\t\t the result:"<<result;
break;
}
default:   //note the colon,not a semicolon
{
cout<<"\n\t\t\t error,bad input";
break;
}
}
cout<<"\n to complete press 0:";
cin>>complete;
}
}
