cout <<"\nCalculator - Enter Number: ";

cin >> num;

cout << "Enter operator : +,-,*,/,^,% : ";

cin >> op;

cout << "enter second number: " ;

cin >> den;

if (op=='+') result=num+den;

if (op=='-') result=num-den;

if (op=='*') result=num*den;

if (op=='/') result=num/den;

if (op=='^') result=pow(num,den);

if (op=='%') result=num/100;

cout << result;

}

while (op!='e') ;

return 0;

}
