read books/watch videos how to write code right

constexpr and noexcept

If you search for code optimisation in YouTube... It will only show how code optimisation works in compiler design, course 🤷🤷😂 But I want real time, that can replace my codes or make it better

never search for this lol!

I am not talking about theorical things, in fact, practical, but that’ll get to you eventually if you are smart enough

😂😂

| is the "bitwise or" operator

actually a logical operator

bad code: int func (int a, int b) { int sum = a + b; return sum; } better int func (int a, int b) { return a+ b; } as a simple example how it could be optimized with experience

No

bad code: int func (int a, int b) { int sum = a + b; return sum; } better int func (int a, int b) { return a+ b; } as a simple example how it could be optimized with experience

| is just bit wise

Do u know about spiral matrix

It usually takes 4 loops. So the interviewer was actually looking for a code which contains only max 2 loops

Yeah sure

bad code: int func (int a, int b) { int sum = a + b; return sum; } better int func (int a, int b) { return a+ b; } as a simple example how it could be optimized with experience

there's actually no difference

mate, we were talking about minimize the lines of code with experience

bad code: int func (int a, int b) { int sum = a + b; return sum; } better int func (int a, int b) { return a+ b; } as a simple example how it could be optimized with experience

there's actually no difference

int add(int x, int y) { return x + y; } Makes more sense as the function name is add

infact the 2nd one is more readable

Isn't there a difference, well we are creating the sum variable and allocating it 4 bytes. And in other case nothing, so it's reducing the time complexity, don't u think?

It's readable in this small code snippet, when the project gets big :(

that's why "//" exists

good code doesnt need coments

good code doesnt need coments

nope

Code could be self explanatory

That's what I was trying to say

A function name should tell what it does

good code doesnt need coments

no comments are acctually important. According to a book i read, there is nothing like self documented code && it's a bad practice not to comment ur code
