Although there are many calculators out there, but none of them was like actual one,
so this is one i have made, although full of bugs, but would work, must try out.

Thanks for having a Look.

Code: Select all

    #include <iostream>
    #include <string>

    using namespace std;

int main()
{
   cout<<"Welcome To The Calculator Full Of Bugs\nBut this is how the actual calculator should work";
        cout<<"\n\t\tBy CyberSpy\n";
   char oprator;
   int val1, val2;
   cout<<"\n\n\nSo What Your Waiting For Start Calculating\n\n\nNote-This Only accepts 2 arguments\n\n\n";
Stuff:
   cout<<endl;
   cin>>val1>>oprator>>val2;
   switch (oprator)
   {
      case '%':
      {
         cout<<"="<<val1%val2;
         goto Stuff;
         break;
      }
      case '/':
      {
         cout<<"="<<val1/val2;
         goto Stuff;
         break;
      }
      case '*':
      {
         cout<<"="<<val1*val2;
         goto Stuff;
         break;
      }
      case '+':
      {
         cout<<"="<<val1+val2;
         goto Stuff;
         break;
      }
      case '-':
      {
         cout<<"="<<val1-val2;
         goto Stuff;
         break;
      }
      default:
      {   
         cout<<"\nSyntax Error!!!\n";
         goto Stuff;
           break;
      }
   }
   
   system("pause");
   return 0;
}

Lovely, you are right, this is a real calc. I found 3 bugs..

if you
enter a+b
then a+b+c
then x*y it spins off into a syntaxx error infinite loop.

It doesnt test for and block division by zero operations before the are sent for calculation.
eg: if(divisor==0)cout<<"WTH no division by zero "; ..then loop back to cin << divisor;
just type it before you get to answer = x/y; because that line will cause the error.

if I enter garbage, it just infinite loops. so maybe you could set up some checks for if(input != 1 || input != 2) etc etc
up unti all the possible characters you want your calc to acknowledge...

good job though, this is the first real calc.. of sorts

thanks
