You can use conditional operator like this,

String result = num % 2 == 0 ? "Even" : "Odd";

Chris

• Oct 28th, 2017

N%2 will give you 0 for even and 1 for odd. The string gives you the address of the start of the string. So for even it prints the string starting at the first character and for odd it starts at the 6th.

You can also use main() simply that means same as int main()..
int main() returns an exit value to compiler and works on most compilers.
And getch() as you mentioned has nothing to do with it. It gets character input on screen or else holds screen in other words

Explanation:
Since i is an unsigned integer it can never become negative.
So the expression i-- >=0 will always be true, leading to an infinite loop.

Why does ++i * ++i give 49 when i=5?

Sheetal Khatri

• Nov 13th, 2017

At first pre increment operator will increment the value of i, here first ++i will make the value 6 then 2nd ++i will make the value 7, now this value will replace the expression. so 7*7=49
Note that ++i (pre increment operator) will first increment and then evaluate.

An array is an array of anything. A string is a specific kind of an array with a well-known convention to determine its length. There are two kinds of programming languages: those in which a string is just an array of characters, and those in which it’s a special type.
