Compiler Warning (level 1) C4717
'function' : recursive on all control paths, function will cause runtime stack overflow
Every path through a function contains a call to the function. Since there is no way to exit the function without first calling itself recursively, the function will never exit.
The following sample generates C4717:
// C4717.cpp
// compile with: /W1 /c
// C4717 expected
int func(int x) {
if (x > 1)
return func(x - 1); // recursive call
else {
int y = func(0) + 1; // recursive call
return y;
}
}
int main(){
func(1);
}
