Why software have bugs?

Software have bugs because of:-

1) Miscommunication or no communication about what an application should or shouldn't do. If the application's requirements will not be clear, software will have bugs.

2) Software complexity - Software complexity is also a contributor for bugs. As a complex application have more paths and it's difficult to manage all efficiently.

3) Programming errors - Programming error, mistakes and logical errors.

4) Changing requirements-If there are many minor changes or any major changes, known and unknown dependencies among parts of the project are likely to interact and cause problems, and the complexity of coordinating changes may result in errors.

5) Time pressures - If we will give our team less than required time , definitely there are chances of errors.
