 # Simple Calculator Program In C++

Here's the code for simple calculator program in C++:

```#include <iostream>

using namespace std;

class calculator
{
public:
int a,b;
cout << "Enter first number:";
cin >> a;
cout << "Enter second number:";
cin >> b;
cout << "addition is :" << a+b;
}
void sub(){
int a,b;
cout << "Enter first number:";
cin >> a;
cout << "Enter second number:";
cin >> b;
cout << "subtraction is :" << a-b;
}
void multi(){
int a,b;
cout << "Enter first number:";
cin >> a;
cout << "Enter second number:";
cin >> b;
cout << "multiplication is :" << a*b;
}
void divi(){
int a,b;
cout << "Enter first number:";
cin >> a;
cout << "Enter second number:";
cin >> b;
cout << "division is :" << a/b;
}
};
int main()
{
calculator calc;
int get;
for(int i=1;i>0;i++)
{
cout << "\n\nPress:\n\t1 : addition\n\t2 : subtraction\n\t3 : multiplication\n\t4 : division\n\t0 : quit\n";
cin >> get;
if(get==1){
} else if(get==2){
calc.sub();
} else if(get==3){
calc.multi();
} else if(get==4){
calc.divi();
} else{
break;
}
}
return 0;
}
```
