An "infinite loop" is a loop in which the exit criteria are never satisfied; such a loop would perform a potentially infinite number of iterations of the loop body. The general problem of determining whether the execution of a loop with given preconditions will result in an infinite loop is undecidable; in other words, there is no algorithm to determine whether an execution of a loop will eventually terminate. This is known as the halting problem.

curious about how "loop = loop" is evaluated in Haskell
I thought expressions like this would cause Haskell to evaluate forever. But the behaviors in both GHCi and the compiled program surprised me.
For example, in GHCi, these expressions blocked until I Control+C, but consumed no CPU. Looked like it was…

I am writing this code for a homework assignment (just starting C++ so please go easy). We've just started while, do-while, and for loops today. The program runs fine except that if you enter a letter when the program asks for an integer, it loops…

C# - How to create a non-detectable infinite loop?
This is just an "I am Curious" question.
In C#-in-depth Jon Skeet says about lambda expressions:
"if there is a nonvoid return type every code path has to return a compatible value." (Page 233)
The footnote then says:
"Code paths throwing exceptions…

Are non-terminating constexpr functions well-defined?
Consider the following code:
constexpr unsigned f(unsigned x)
{
while (x & 1) x *= 3;
return x;
}
int main()
{
char a[f(2)];
char b[f(1)];
}
In case it isn't obvious: for odd integers x, the function f never terminates.
When I…
