If you know that a function is even (or odd), it may simplify the analysis of the function, for several purposes. One example is the calculation of definite integrals: for an odd function, the integral of a function from (-x) to (x) (note 1) is zero; for an even function, this integral is twice the integral of the function from (0) to (x).
Note 1: That is, the area under the function; for negative values, this "area" is taken as negative) is

It is an odd function. Even functions use the y-axis like a mirror, and odd functions have half-circle rotational symmetry.
how to use even and odd number with for loop and if condition plz dont use "int"..
There are no 5 odd numbers that when added together make 30.Two odd numbers added together make an even numberAn odd number plus and even number makes an odd number.From the five odd numbers:Take two of them and add them together getting an even number and four odd numbersAdd another of the odd numbers to this even number and you will have three odd numbersAdd two of these together and you will have one even and one odd number.Finally add these odd and even numbers together and the result will be an odd numberBut 30 is an even number, so cannot be the sum of five (or any odd number of) odd numbers.
If the factorization includes the number 2, it's even. If not, it's odd.
3 + 3 = 6
