the following code is meant to add two LargeNum type class constructs and add them.
class LargeNum
{
private:
NumNode* first;
NumNode* last;
bool isNeg;
public:
int value;
NumNode* next;
//todo constructor, inital point
//constructor
LargeNum(int value);
LargeNum(string value);
//destructor
~LargeNum();
//members
void Append(int value);
string ToString()const;
const LargeNum LargeNum::operator+ (const LargeNum& ln2)
{
LargeNum result = value + ln2.value;
return result;
}
//LargeNum add(LargeNum val1, LargeNum val2);
};
When I try and add the two in the main.cpp then I get integral or unscoped enum type error and it references the second pointer. See below.
LargeNum Result_1 = L1 + L2;
with the error falling on l2. Thoughts?
Not sure exactly what is the error that you get, however, the code below compiles just fine (a simplified version of your class)
#include <iostream>
#include <string>
using namespace std;
class LargeNum
{
public:
int value;
//todo constructor, inital point
//constructor
LargeNum(int value):value(value){};
LargeNum(string value){};
//destructor
~LargeNum(){};
//members
const LargeNum operator+ (const LargeNum& ln2)
{
LargeNum result = value + ln2.value;
return result;
}
};
int main()
{
LargeNum L1=4;
LargeNum L2=5;
LargeNum L3=L1+L2;
cout <<L3.value;
}
and outputs 9 as a result. Btw, you don't need the extra LargeNum::
qualification when declaring operator+()
. Check if it compiles without, if not, please post the whole code (with implementation) in a single file.
