Thread: 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 ....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);
	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)
	{
			
    cout<<"Please choose an operation"<<endl
	    <<"Press 1 Add"<<endl
     	<<"Press 2 Subtract"<<endl
	    <<"Press 3 Divide"<<endl
		<<"Press 4 Multiply"<<endl
    	<<"Press 5 Compare"<<endl
    	<<"Press 6 Square root"<<endl
	    <<"Press 7 Power"<<endl
    	<<"Press 8 Quit"<<endl;
	cin>>choice;
		
	if(choice==1)
	{
	cout<<"The answer is:"<<add()<<endl;
	}

	else if (choice==2)
	{
	cout<<"The answer is:"<<subtract()<<endl;
	}

	else if(choice==3)
	{
	cout<<"The answer is:"<<divide()<<endl;
	}

	else if (choice==4)
	{
	cout<<"The answer is:"<<multiply()<<endl;
	}
	else if (choice==5)
	{
	compare();
	}

	else if (choice==6)
	{
	sqrt();
	}

	else if (choice==7)
	{
	power();
	}
	
	else
	{
		cout<<"Error in input data"<<endl;
	}//end of if
	
}//end of while
	if(choice==8)
	{cout<<"Thank you for using my Calculator program."<<endl;}
	
}//end of menu function

Although you can pseudo-code/flowchart your existing code, it would run counter to your assignment.

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.

uh huh...thanx y
u sound like a pro...which i am not.....
far from...
