using namespace std;
int main()
{
int First;
int Second;
int x ;
cout << endl;
cout << " Press 1 for Addition "<<endl <<endl;
cout << " Press 1 for Addition "<<endl;
cout << " Press 2 for Subtraction "<<endl;
cout << " Press 3 for Multiplication "<<endl;
cout << " Press 4 for Division " <<endl;
cout << " Enter You Choice: ";
cin >> x;
switch (x)
{
case 1:
cout << " Enter Value of First Number: ";
cin >>First;
cout << " Enter Value of Second Number: ";
cin>>Second;
cout <<" Result of Addition is: " <<First + Second<< endl ;
break ;
case 2 :
cout << " Enter Value of First Number: ";
cin >>First;
cout << " Enter Value of Second Number: ";
cin >>Second;
cout << " Result of Subtraction is: "<<First - Second<< endl;
break;
case 3 :
cout << " Enter Value of First Number: ";
cin >>First;
cout << " Enter Value of Second Number: ";
cin>>Second;
cout <<" Result of Multiplication is: " <<First * Second<< endl;
break;
case 4 :
cout << " Enter Value of First Number: ";
cin >>First;
cout << " Enter Value of Second Number: ";
cin>>Second;
if (Second==0)
{cout << " Infinity" ;}
else
{cout << " Result of Division is: "<<First / Second<<endl;}
break;
default:
cout << " Invalid Entry "<<endl;
break;}
return 0;
