Suppose we are working in a setting where we only have integers and the operations that we are doing on them are multiply, add, subtract and comparisons between them

In such a scenario is it safe to replace all integers with doubles? (Safe in the sense of precision issues)

Can someone tell what are the compilation flags that you use in Windows-10 and also the compiler which you use. (The main thing I want is how to catch out of arrays accesses and similar stuff and catching exceptions..). You may also share your IDE if you want . Thanks Friends..

I have noticed that in geany(windows-10) '.' && '>' don't work properly.When we press the key once the respective character doesn't get printed on to the screen and we are required to press the key twice. And also '_'(underscores) aren't visible(they exist but are invisible for some reason). Can someone provide a solution to these problems. Any help is appreciated.

Can someone help me with this question Chef and Clothes? I am really missing some observations here in this question. Can someone help me to figure it out?

Recently I came across this blog Efficient and Easy segment trees. After reading this I felt that the normal implementation with 5 arguments is easier to understand and implement(in my opinion). I want to know which of the implementations of segment-tree is better so that if the one written in the blog is better I will try to learn it. (better in the sense that it can be easily be applied in some new question)
