1 Basic explanation:extern can be placed before a variable or function to mark the definition of a variable or function in another file, prompting the compiler to find its definition in other modules when it encounters this variable and function.

Use the operator overloading method in C + + to implement mathematical operations between large numbers, including addition, subtraction, multiplication, division, n-th, modulo, size comparison, assignment and overload of input stream, output stream.
