normal C: the programmer will write what type they want, easy
C++: we're fancy, the compiler can, like, infer type stuff on the left side of an assignment based on the type on the right side! it might make it a little harder to figure out stuff like iterator types without a fancy IDE but it will be worth the convenience if the feature isn't overused
Rust: you're like a baby, hold my beer, we will infer part of the type of a variable based on WHAT HAPPENS DOZENS OF STATEMENTS FURTHER DOWN mwahaHAHAHAHAHA good luck trying to read this code in one pass suckers

in rust it is apparently normal that you can create a vector, call functions on it that resize it and whatnot, and then later insert elements, and the element insertion implicitly provides the type and element size needed to compile preceding method calls

@jann Automatic type deduction and conversion, so great when they work, and so painful when they do not! An @ACCU _CVu_ journal article recently spot-lighted how weird C++ implicit type conversions can be. Somehow I find remembering which types are trivially constructible from one another difficult.
