I am not sure what you mean by the question.
Integers have been around forever. People started to count probably about 50,000 years ago (only very small amounts at first). They started writing them down about 5,000 years ago. Different people used different ways of writing numbers. The current system of writing them down is Arabic and was invented around the year 500 AD.

Which of the following three C code snippets WILL NOT read a date as three integers as follows: int day, month, year;
Negative integers, zero and the positive integers, together form the set of integers.

TrueYes.All rational numbers are a fraction of one integer (numerator) over another integer (denominator).All integers can be made into a[n improper] fraction over a denominator of 1.Thus all integers are rational numbers
Those letters are indeed often used to represent integers. But in practice, it's best to always check what assumptions are made. If certain variables (letters) are meant to be integers only, for example for some theorem, this should be stated explicitly.
Non-positive integers are zero and the negative integers.
