Integer overflow

(1) overflow
#include <limits.h> #include <stdio.h> int main() { int a = INT_MAX; printf("%d\n", a); // 2147483647 ++a; printf("%d\n", a); // -2147483648 return 0; }	import std.stdio; void main() { int a = int.max; writeln(a); // 2147483647 ++a; writeln(a); // -2147483648 }

It's possible to detect overflow. Use the core.checkedint module.
