NEED HELP! :( Simple Calculator using Pointers.

Need help making a Calculator program.
I need help on the function I have set, idk if I'm doing it correct or not. and how to have a function call for it. I tried using Calculate();

Quote:

- Create a function called "Calculate" that takes in two integer pointers and - char variable as parameters. This function will return an integer value.
- Save the returned value into a new int variable called "result"
- Point "integerPointer" to the address of "result" and display the dereferenced value for integerPointer.

is what is needed.

Code:

---

#include<iostream>
using namespace std;
int integerVariable1;
int integerVariable2;
char operation;
int result;
int Dothemath;
int Calculate(int *integerPointer,char operation);
int main()
{
        char again = 'y';
while (again == 'y')
{
        cout<<"Please enter your first number:";
        cin>>integerVariable1;
       
        cout<<"Please enter the desired operation:";
        cin>>operation;

        cout<<"Please enter your second number:";
        cin>>integerVariable2;

        int* integerPointer=0;
        integerPointer=&integerVariable1;

        cout<<*integerPointer<<operation;
        integerPointer=&integerVariable2;
        cout<<*integerPointer;
        cout<<"=";
        integerPointer=&result;
        cout<<*integerPointer;
        cout<<"\nCare to try again? (y/n)";
    cin>>again;
}
   
  return 0;
}
 int Calculate(int *integerPointer,char operation)
{
        int result;
  if(operation=='+')
  {
          result=*integerPointer+*integerPointer;
  }
  if(operation=='-')
  {
  result=*integerPointer-*integerPointer;
  }
  return result;
 }

Something like

Code:

---

        cout<<"Please enter your first number:";
        cin>>integerVariable1;
       
        cout<<"Please enter the desired operation:";
        cin>>operation;

        int result = Calculate( &integerVariable1, operation );

I think with that, you should be able to get pretty close to the answer.

Code:

---

cout<<"Please enter your first number:";
        cin>>integerVariable1;
       
        cout<<"Please enter the desired operation:";
        cin>>operation;

        int result = Calculate( &integerVariable1, operation );

k I see this and tried it it will include the variable 1 and operation, into the calculate but it wont let me take the variable two instead it just takes in variable 1 and uses it twice
how am I supposed to make it similar to

Code:

---

int result = Calculate( &integerVariable1, &integerVariable2,operation );

---

Where are your edits to the Calculate function, so that it expects and uses another parameter?
