What does C++ do with overflow?
What does Java do with overflow?

When C++ has a overflow error, i think it goes to the smallest possible number and adds from there, but I’m not exactly sure. I don’t know how java handles this problem?

    In n3242 of the C++ standard

    5 Expressions [expr]

    Paragraph 5.4:

    If during the evaluation of an expression, the result is not mathematically defined or not in the range of representable values for its type, the behavior is undefined. [ Note: most existing implementations of C++ ignore integer overflows. Treatment of division by zero, forming a remainder using a zero divisor, and all floating point exceptions vary among machines, and is usually adjustable by a library function. —end note ]"

    From OP
