If during the evaluation of an expression, the result is not mathematically defined or not in the range of representable values for its type,. [...] Unsigned integers, declared,where n is the number of bits in the value representation of that particular size of integer ", and the result ...
See §6.3.1 Arithmetic operands and §6.3.1.1 Boolean, characters, and integers for more information about 'integer promotions'. The following may be used in an expression wherever an int or unsigned int may be used: An object or expression with an integer type (other than ...
The compiler will not warn you if the expression has only one operand, a signed type, whose value fits in the destination type. Let’s discuss an example to understand better how the compiler warns: #include<iostream>#include<string>using namespace std;inthelloWorld(string input);intmain(){...
This is the threshold at which "adding more than this many times may cause int32_t/int64_t to overflow." It might be better to clarify that this refers to the number of times, not the maximum value that can be added. If I directly translate the expression I came up with in Japanese...
The C++20 standard makes this blanket statement: “If during the evaluation of an expression, the result is not mathematically defined or not in the range of representable values for its type, the behavior is undefined”. Colloquially, this is calledoverflow. ...
Another possibility is to use a regular expression to check if a strings is a valid floating point number, like shown in this post. However, using strtod() or std::from_chars() might be better, and as a benefit those also return the actual double. Error handling If you want to use ...

Should the precision of int be equal to unsigned int, u will be promoted to a signed int and you will get the value -4444 from the expression (u+i). Now, should u and i have other values, you may get overflow and undefined behavior but with those exact numbers you will get -4444...
