What happens if a value stored in an int variable gets too big?

If a value stored in an int variable exceeds its maximum limit, it typically results in integer overflow. In many programming languages, this causes the value to wrap around to the minimum value representable by the int type, leading to unexpected results. For example, if an 8-bit signed integer exceeds 127, it might roll over to -128. The behavior can vary by language and implementation, so it's essential to check for overflow conditions when performing arithmetic operations.
