What's ||?I don't understand about c++:-[

Answer 1

|| is the logical or operator. The result is true if either operand is true.

For example:

//returns true if the point (x, y) is on the vertical or horizontal axis
bool onAxis(int x, int y) {
if ((x == 0) || (y == 0)) {
return true;
} else {
return false;
}
}

Answer 2

why don't u refer to ur book?

Answer 3

Meaning “or” in contrary to “&&” which means “and”

Answer 4

|| is a logical operator for 'or'. Ex. you want to eat apple and you have two fruits say x and y. You will say "if either x or y is apple i will eat it." so we can write it in c++ like :

if (x=="apple"||y=="apply")
{//EAT IT
}

the code in the braces after if condition will execute if any of the fruit is apple.
