Function
friend BigInteger operator + ( const BigInteger& val1, const BigInteger& val2 );
Return a BigInteger object with value = val1 + val2.
Parameters
Two BigInteger objects val1 and val2.
Return value
A BigInteger object with value = val1 + val2.
Example
#include <iostream>
#include <string>
#include "HKUAL_BigInteger.h"
using namespace std;
using namespace HKUAL;
int main() {
BigInteger bigInt1( "10000" );
BigInteger bigInt2( "20000" );
BigInteger bigInt = bigInt1 + bigInt2;
cout << "bigInt = " << bigInt << endl;
return( 0 );
}
