Definition: In computer science, an "immantiled" function or subroutine is a function that has been executed multiple times and does not return any value. This means that the function was called many times with different arguments, but it never returned a result. For example, consider the following code: ``` void func(int arg1, int arg2) { // ... } int main() { func(5, 6); // Calls func 5 times return 0; }
