Suggestions

Hey everyone! I hope you're all doing well. Currently, I'm reviewing a C++ roadmap and I noticed something. In the 'basic operations' section, they talk about 'arithmetic operators', 'logical operators', 'bitwise operators', and 'loops like for/while'. But then, there's another section called 'functions' that covers 'operators' and 'lambdas'. It seems like the operators mentioned in the 'functions' section are the same as the ones discussed in the 'basic operations' section. I think it would be better to talk about 'overloading operators' in the 'functions' section instead. Also, I believe it would be helpful to create a new section called 'control flow and statements' to discuss loops like 'for/while/do while' and conditions like 'if/else/switch/go to'. What do you think?
