ooplab4.cpp

This code performs the arithmatic operations. This is simply an calculator. Very useful code for the

#include<iostream.h>
#include<conio.h>
#include<math.h>

class matlab

private:
	int operation, choice;
	float a,b,c,z;
public:
	float arith(float x, float y, int operation)
	{
		switch (operation)
		{
		case 0:
			 z=x+y;
			 break;
		 case 1:
			z=x-y;
			 break;
		 case 2:
			 z=x*y;
			 break;
		 case 3:
			 z=x/y;
			 break;
		  }
		  return z;
	}
	float trig(float x, int operation)
	{
		if(operation==0)
			{
			 z=cos(x);

			}
	return z;}
	void ui()
	{
	clrscr();
	cout<<"Menu"<<endl;
	cout<<"press 1 for arithmatic operations"<<endl;
