<>1. 一维数组遍历
* 数组遍历一般使用foreach或者使用for循环
* for和foreach都使用 begin … end 表示作用范围
<>1.1 foreach
int array[3] = '{9, 5, 8}; foreach(array[i]) $display("array[%0d] = %d", i,
array[i]);
* foreach循环相当于从数组的宽度的左端点,向数组宽度的右端点循环。
* int array[3]; 等价于 int array[0:2]; 即索引变量从0开始,遍历到2。
<>1.2 for循环
* 注 意 f o r 循 环 需 要 自 己 声 明 循 环 变 量 \color{red}{注意for循环需要自己声明循环变量} 注意for循环需要自
己声明循环变量 int array[3] = '{9, 5, 8}; for(int i=0; i < $size(array); i++) $display(
"array[%0d] = %d", i, array[i]);
<>2. 多维数组的遍历
<>2.1 foreach
* 注意循环变量为 [ i , j ] \color{red}{[i,j]} [i,j],而索引的时候为 [ i ] [ j ]
\color{red}{[i] [j]}[i][j]
* 会先遍历 j,然后遍历 i int md[2][3] ='{'{0,1,2},{3,4,5}}; foreach(md[i,j]) $display(
"md[%0d][%0d] = %0d", i,j,md[i][j]);
<>2.2 for循环
int md[2][3] ='{'{0,1,2},{3,4,5}}; for(int i=0;i < $size(md); i++) for(int j=0;
j< $size(md[i]); j++) $display("md[%0d][%0d] = %0d", i,j,md[i][j]);
