We use this with small arrays. int num [5] = {1, 1, 1, 1, 1}; This will initialize the num array with value 1 at all index. WebIn C, you cannot modify the code so that it reads: ray r; sphere s; position_3d pos = getIntersectionPosition (r, s); position_3d func (void) { return pos; } That then gives a warning: sphere.c:43: error: initializer element is not constant If you compile with g++ instead of gcc, though (and remove the C-specific options, leaving): green deal office
