c++ - For loop returns ** value. Please explain -

can explain please why output of next code **?

#include <iostream> using namespace std; int main() { (float val = -10.0; val < 100; val = -val * 2) { if (val < 0 && -val >= 40) break; cout << "*"; } homecoming 0; }

would please go bit bit in explanation? much

iteration 1 val -10 if ((-10 < 0) && (+10 >= 40)) false so doesn't break out of loop * printed loop condition: (-10 < 100) true so loop continues val updated: val = -val * 2 val = +10*2 = 20 iteration 2 val 20 if statement short-circuits false due (20 < 0) beingness false so doesn't break out of loop * printed loop condition: (20 < 100) true so loop continues val updated val = -20*2 = -40 iteration 3 val -40 if((-40 < 0) && (+40 >= 40)) true so breaks out of loop before printing again
