Thread: Whats wrong with this program!?

Code:

#include <iostream.h>
int main()
{
   int a,b,c;
   cout<<"Welcome to Adam Petrosh's kinda kool kalkulator! Enter 1 for subtraction, 2 for addition, 3 for multiplying, and 4 for division: ";
   cin>>a;
   if(a=1)
   {
      cout<<"You have chosen Subtraction!";
      cout<<"Please enter the two numbers you want to subtract(seperate them with a space): ";
      cin>>b-c;
      cout<<"Prossessing.... complete!";
      cout<<"The answer is ";
      cout<<(b-c);
      cin.get();
   }
   if(a=2)
   {
      cout<<"You have chosen addition!";
      cout<<"Please enter the two numbers you want to add(seperate them with a space): ";
      cin>>b,c;
      cout<<"Prossessing... complete!";
      cout<<"The answer is ";
      cout<<(b+c);
      cin.get();
   }
   if(a=3)
   {
      cout<<"You have chosen multiplication!";
      cout<<"Please enter the two numbers you want to multiply(seperate them with a space): ";
      cin>>b,c;
      cout<<"Prossessing... complete!";
      cout<<"The answer is ";
      cout<<(b*c);
      cin.get();
   }
   if(a=4)
   {
      cout<<"You have chosen division!";
      cout<<"Please enter the two numbers you want to multiply(seperafe them with a space): ";
      cin>>b,c;
      cout<<"Prossessing... complete!";
      cout<<"The answer is ";
      cout<<(b/c);
      cin.get();
   }
   else
   }
      cout<<"I SAID 1, 2, 3, OR 4 YOU IDIOT! PROGRAM TERMINATING!";
      cin.get();
   }
   cin.get();
   return 0;
