char op;
float num1, num2,num3,num4,num5;

cout << "Enter operator either + or - or * or /: ";
cin >> op;

cout << "Enter five operands: ";
cin >> num1 >> num2 >> num3 >> num4 >> num5;

switch(op)
{
case '+':
cout << num1+num2+num3+num4+num5;
break;

case '-':
cout << num1-num2-num3-num4-num5;
break;

case '*':
cout << num1*num2*num3*num4*num5;
break;

case '/':
cout << num1/num2/num3/num4/num5;
break;

default:
// If the operator is other than +, -, * or /, error message is shown
cout << "Error! operator is not correct";
break;
