The amount of code you can copy without infringing copyright is not fixed and typically falls under 'fair use' considerations. Factors like the purpose of use, the nature of the work, the amount copied, and its impact on the market value are taken into account. Always seek permission when in doubt or consider using code licensed for public use, such as those under MIT or Apache licenses. This approach helps you stay on the right side of the law while respecting intellectual property.
