writing the pseudocode........functions

have an assign.
have to do an ipo chart.......unsure how to factor in the functions into the algorithm
i have to do both flowchart and pseudocode....... :(

the thing is......i've already written the code :confused: ....but i not sure what's expected in this ipo chart...........help?

this is my code:

Code:

---

#include <iostream>
#include <cmath>
using namespace std;


double add()
{
        double N1=0.0, N2=0.0, sum;
        cout<<"Enter 2 numbers"<<endl;
        cin>>N1>>N2;
        sum=N1+N2;
        return sum;

}//end of function add

double subtract()
{
        double N1=0.0,N2=0.0, diff;
        cout<<"Enter 2 numbers"<<endl;
        cin>>N1>>N2;
        diff=N1-N2;
        return diff;
}//end of function subtract

double divide()
{
        double N1=0.0,N2=0.0,ans;
        cout<<"Enter 2 numbers"<<endl;
        cin>>N1>>N2;
        ans=N1/N2;
        return ans;
}//end of function divide

double multiply()
{
        double N1=0.0, N2=0.0,prod;
        cout<<"Enter 2 numbers"<<endl;
        cin>>N1>>N2;
        prod=N1*N2;
        return prod;
}//end of function multiply

void compare()
{
        double N1=0.0,N2=0.0;
        cout<<"Enter 2 numbers"<<endl;
        cin>>N1>>N2;
        if(N1>N2)
        {
                cout<<"The 1st number is larger"<<endl;
        }
        else if(N1<N2)
        {
                cout<<"The 2nd number is larger"<<endl;
        }
        else
        {
                cout<<"The numbers are equal"<<endl;
        }
}//end of function compare

float sqrt()
{
        float SQR=0.0;
        cout<<"Enter the number"<<endl;
        cin>>SQR;
        SQR=sqrt(SQR);

        return SQR;
}//end of square root function

        return ans;

A small bit of constructive criticism...

Although you can pseudo-code/flowchart your existing code, it would run counter to your assignment. Additionally, I would recommend completely ignoring your current code and pseudo-code / flowchart your menu from scratch. If you do that, I think you'll find a lot of redundant code in your current incarnation (hence the reason for pseudo-coding before authoring to begin with) :).

Hint... focus on learning to pseudo-code switch statements, and passing values to functions, as well as returning values.
