Difference between int and var in C++?

Question

int and var both define value holders such as x
However, do they both mean the same thing?
Or does int define type and var intoduces variable?

Answer 1

C++ doesn't have var.

int holds numbers that doesn't have floating point.

var detect what type you assigend to it.

var x = 64; ( int )
var y = 52.6; ( double )

similar to ( in C++ )

auto x = 64;
auto y = 52.6;

the closest you can get to var in C++ is to use auto and std::variant or std::any from C++17.

Answer 2

what about C

Answer 3

tbh I'm not sure if C has auto or not. but it surely doesn't have var.

var is known well at most scripting languages. ( js, lua, python, etc )
