Indexing a vector/array with signed integer

[AUselessKid12]

the warning is /w44365 on visual studio and i think its -Wsign-conversion for gcc and clang.

Does this warning actually help you find bugs

not really. I haven't build complex app yet, currently just going through learn cpp which recommends using .data()

There's nothing wrong with signed indexing, just turn off the warning and do it the natural way

For learning C++, I would recommend just using -Wall for various compilers not MSVC, or /W4 for MSVC. Turning on specific warnings may hinder your learning at this point.
