Explanation / Answer
Hi,
Below is the solution to your question:
/*Simple calculator using Switch statement*/
# include <iostream>
# include <cmath>
using namespace std;
int main()
{
char ch;
float number1,number2;
cout << "Enter operator either +, -, * or /: "<<endl;
cin >> ch;
cout << "Enter the two operands: "<<endl;
cin >> number1 >> number2;
switch(ch) {
case '+':
cout << number1+number2;
break;
case '-':
cout << number1-number2;
break;
case '*':
cout << number1*number2;
break;
case '/':
if(number2==0)
{
cout<<"Invalid,Divide by zero is not possible !!!"<<endl;
}
cout << number1/number2;
break;
default:
/* If operator is anything other than +, -, * or /, error message is shown */
cout << "Invalid operator"<<endl;
break;
}
return 0;
}
Output:
Enter operator either +, -, * or /: -
Enter the two operands:
8
3
8 - 3 = 5
Hope that helps...HAPPY ANSWERING!!!!!!!
