No, it is not.
An integer array consists of only integer numbers, for instance, if you have the array of size 5 with integer type date int_array[5] it means that your first element int_array[0] is an integer number like 1, or 15 and so on. The same is true for other elements too; int_array[1](int_array[2], int_array[3], int_array[4]) might be any integer element and so on.
It may come as a surprise, but the answer is 5.
The magnitude of an integer is the value of the integer with a positive (plus) sign. |5| = +5 = 5 |-5| = +5 = 5
-5 is an integer. The inclusion of "of 5" in the question is irrelevant.
It is already an integer as 5
15/3 = 5 5 is an integer.
Yes; a number that has no decimal part such as 5**.5** is considered an integer.
positive 5 and negative 5. -5 +5
coefficients
zero is the additive identity element.
No. The numeral '5' is an integer, though.
5 of course: look up the definition of "integer".
