I'm relatively new to programming, but am really enjoying it. I have taken a couple of classes but mostly code for fun (for now). I decided to make a program implementing some basic functions, switch statements, and user input. Please leave any feedback on how to make this program better.



I understand that I am not actually using the defined functions (add, subtract, etc.), but I put them in there with the intent of using them, I just don't know how.



#include <iostream>
using namespace std;

int add (int x, int y){
return x+y;
};

int divide (int x, int y){
return x/y;
}

int multiply (int x, int y){
return x*y;
}

int subtract (int x, int y){
return x-y;
}


int main(){

int n1;
int n2;
int user14 = 0;

SomeLine:
cout << "Enter your 2 numbers: "<< endl;
cin >> n1;
cin >> n2;


cout << "Ok, now what do you want to do with those numbers? "<< endl;

cout << "1) Add: " << endl;
cout << "2) Divide: "<<endl;
cout << "3) Multiply: "<< endl;
cout << "4) Subtration: "<< endl;

cin >> user14;

switch (user14)
{
case 1:
cout << n1+n2 << endl;
break;
case 2:
cout << n1/n2 << endl;
break;
case 3:
cout << n1*n2<< endl;
break;
case 4:
cout << n1-n2 << endl;
break;

}

char userchoice;
cout << "Would you like to perform any other operations? y/n "<< endl;

cin >> userchoice;

if (userchoice=='y'){
goto SomeLine;
}
else if(userchoice=='n'){
goto Exit;
}

Exit:
return 0;

};
