    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);
    	cout<<"The answer is: "<<SQR<<endl;
    	return SQR;
    }//end of square root function
    double power()
    {
    	double N1=0.0,N2=0.0,ans;
    	cout<<"Enter 2 numbers. The second number being the POWER."<<endl;
    	cin>>N1>>N2;
    	ans=pow(N1,N2);
    	cout<<endl<<"The answer is: "<<ans<<endl;
    	return ans;
    }//end of function power
    
    
    void menu()
    {
    	int choice;
    		
    	while(choice!=8)
    	{

    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.
