Answer:
In Function library you would find the use in Formula function
Answer:
D. Low-level components are combined into clusters that perform a specific software sub-function
Explanation:
Normally, regression testing are done on a manual basis by simply re-executing a subset of the entire available test cases or it can be done automatically by utilizing playback tools or automated capture. Hence, from the options, a combination of low-level components into clusters that perform a specific sub-function does not align with how regression testing are done either manually or automatically.
Answer:
The buffer has room for 499 characters (you always have to reserve 1 for the terminating \0 character).
The code copies all characters passed in the commandline (argv[1]) into this buffer without checking. If there are more than 499 characters supplied, these will be copied into a memory location that is not intended for it. This will probably cause your program to crash, but if the extra data is somehow executed by the processor as if it were a program, this could be a way to sneak a virus into your computer.
So, while copying data, it is important to always limit the maximum amount to the allocated space.
Answer:
Differences between Object Oriented Programming and Structured Programming
1. Structured programming focuses on process/logic then data while OOP(Object Oriented programming) focuses on data.
2.OOP supports Inheritance,Encapsulation,Abstraction,Polymorphism while structured programming does not supports these.
3.Structured programming follows top-down approach while OOP follows bottom-up approach.
4.OOP is more secured than structured programming because it supports Abstraction (data hiding).
