Breaking out of a foreach loop
When using a Cartesian or multigrid, the break
statement does not directly exit the foreach loop. But is does on a tree-grid, making the behaviour grid dependent.
#include "grid/multigrid.h"
int main() {
init_grid (4); // a 4 x 4 grid;
int j = 0;
foreach() {
printf ("This is printed %d time(s)\n", ++j);
break statement not within loop or switch
break;
}
}
output
The line is printed N
times as it break
s only the row iterator loop. See here.
