### Cube and Power without built-in functions Cpp / C++

This Cpp program is for using the Math functions without the Math.h class. This is a part of Mumbai University MCA Colleges C++ / CPP Programs MCA.

The below program performs the operations of finding cube and power of a number without the built-in math functions. The Functions for the same are created by the programmer.

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

class Math_1
{
int cu,num,base,pow,res;
public :
Math_1(){}
Math_1(int n)
{
num=n;
}
Math_1(int b,int p)
{
base=b;
pow=p;
}
~Math_1(){}
void cube();
void power();
};

void Math_1 :: cube()
{
cu=num*num*num;
cout<<endl;
cout<<"Cube of "<<num<<" : "<<cu;
}

void Math_1 :: power()
{

for(int i=0;i<pow;i++)
res=res*base;
cout<<endl;
cout<<"Result : "<<res;
}

void main()
{
int num,b,p,ch;
clrscr();
cout<<"1. Cube"<<endl;
cout<<"2. Power"<<endl<<endl;
cout<<"3. End";
while(1)
{
cout<<"\n\nEnter your choice : ";
cin>>ch;
switch(ch)
{
case 1:
cout<<"Enter Number : ";
cin>>num;
Math_1 m1(num);
m1.cube();
break;

case 2:
cout<<"Enter Base : ";
cin>>b;
cout<<"Enter Power : ";
cin>>p;
Math_1 m2(b,p);
m2.power();
break;

default :
cout<<"Please Enter Right Choice.";
exit(0);

}
}
getch();
}
