Extracted text: Task 1 Biglnt class is used for the mathematical operations that involve very big integer calculations that are outside the limit of all available primitive data types. For example, factorial of 100 contains 158 digits in it so we can't store it in any primitive data type available. We can store as large Integer as we want in it. Your goal is to overload the operators for a generic “Biglnt" class. You will need to write two files (Biglnt.h and Biglnt.cpp) and test your program by writing main function. Your implemented class must fully provide the definitions of following class (interface) functions. class BigInt { //think about the private data members public: BigInt (int val BigInt (const string& text); BigInt (const BigInt& copy); // copy constructor 0); %3D BigInt operator+(const BigInt& val) const; BigInt operator+(int val) const; BigInt operator-(const BigInt& val) const; BigInt operator-(int val) const; // Logical Operators bool operator==(const BigInt& val) const; bool operator!=(const BigInt& val) const; // Unary Operators BigInt& operator++(); // Pre-increment Operator BigInt operator++(int); // Post-increment Operator BigInt& operator--(); // Pre-decrement Operator BigInt operator--( int ); // Post-decrement Operator operator string(); -BigInt (); // destructor }; // return value of the BigInt as string ostream& operator< (ostream&="" output,="" const="" bigint&="" val);="" outputs="" the="" bigint="" istream&="" operator="">>(istream& input, BigInt& val); // inputs the BigInt Arddress
