javascript - Ocanvas creation inquiry -


i'm still little fuzzy on ocanvas, i'm new it. know it's not best choice or documented, have potential job depends on me learning it.

i wondering ocanvas.create(); should placed. right have function called main(); in html head , html body runs every time body loops. seems ocanvas.create(); works if place in main(); function, creating canvas every time body loops?

can explain bit more 'every time body loops'? have settimeout/setinterval/requestanimationframe runs main many times? in case, run ocanvas.create outside of main , access inside main when needed.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
