What is the purpose of table in computer?

Answer 1

I going to assume you are asking what is the purpose a table in a computer as it relates to programming. "Table" in programming is a another name for "array". An array can be thought of as a storage method for a series of similar data items that are accessed via a subscript value. Here is an example of a very simple array with first 3 subscripts: Array Name = First Names (contains 5000 data items) data item 1 "tom" data item 2 "frank" data item 3 "steve" .............................. data item 5000 'zeke" Now, in my program I could refer to each data item as "data item 1" or "data item 2", and so on. This is very tedious and would generate thousands of lines of code if I wanted to reference all 5000 data items. A much better way would be to reference the data item by First Names (the array name) using a subscript value of 1 to 5000. I could set a the subscript value to 1 ( I will use the variable called sub) and do something like move First Names (sub) to print. Then I would just keep adding 1 to sub and execute the same move over and over again until all 5000 are printed using the same move.
