Big number operations

Big number operations

I have been plagued by big number operations for so long as I have been dealing with computers. Specifically, I am very frustrated with some specific aspects. The data types in my computer have restrictions on the numbers supported by numbers. For example:

Long int a = 0;

Here, a can represent a maximum of 9 long integer numbers. To store numbers with more than 9 digits, the most feasible method is to store the values of each digit using arrays. Therefore, you can use an array to complete the corresponding operation in case of a large number operation.
