ok me and my friend have been working on the program and are having trouble getting the arrays to pass to the functions and dont know where the issue is.


#include <iostream>
using namespace std;


class Integer{

public:
Integer();
Integer(Integer& a);
Integer operator +(const Integer &);
Integer operator -(const Integer &);
bool operator<(Integer)const;
void SetArr();
void print();
void addNumbers();
void subNumbers();

private:
bool sign;
int size;
int size2;
int size3;
char * arr1;
char * arr2;
char * arr3;


};

int main()
{
Integer sum,diff, in1,in2;
in1.SetArr();
/*in2.SetArr();

in1.addNumbers();
in1.print();
in1.subNumbers();
in1.print();*/




}
Integer::Integer()
{
size=0;
arr1=NULL;
}
Integer::Integer(Integer& a)
{
a.size=0;
a.arr1=NULL;
}
void Integer::SetArr()
{
cout<<"How many digits is the number?"<<endl;
cin>>size;
int* arr1=new int[size];
cout<<"Enter the sequence of the "<<size<<" integers"<<endl;
for(int i=(size-1);i>=0;i--)
cin>>arr1[i];

cout<<endl;
for(int i=0;i<size;i++)
cout<<arr1[i];


cout<<endl<<"How many digits is the second number?"<<endl;
cin>>size2;
int* arr2=new int[size2];
cout<<"Enter the sequence of the "<<size2<<" integers"<<endl;
for(int i=(size2-1);i>=0;i--)
cin>>arr2[i];

cout<<endl;
for(int i=0;i<size2;i++)
cout<<arr2[i];

if(size>=size2)
size3=size+1;
else
size3=size2+1;

int* arr3=new int[size3];


int carry=0;
for(int i=0;i<size3;i++){
arr3[i]=48+(arr1[i]+arr2[i]-2*48+carry)%10;
carry=(arr1[i]+arr2[i]-2*48+carry)/10;
}

cout<<endl<<"Addition:"<<endl;
for(int i=(size3-1);i>=0;i--)
cout<<arr3[i];

cout<<endl<<endl;




for(int i=0;i<size3;i++){

}
}
cout<<endl;
for(int i=0;i<size3;i++)
cout<<arr3[i];
cout<<endl<<"Subtraction:"<<endl;
for(int i=(size3-1);i>=0;i--)
cout<<arr3[i];

}
void Integer::print()
{
for(int i=0;i<size;i++)
cout<<arr1[i];
}

void Integer::addNumbers()
{
int carry=0;
for(int i=0;i<size;i++){
arr3[i]=48+(arr1[i]+arr2[i]-2*48+carry)%10;
carry=(arr1[i]+arr2[i]-2*48+carry)/10;
}
}
