可以使用 switch-case 语句来代替多个 if-elseif 分支,使代码更简洁易懂,如下所示:
```
switch (jjz)
case 1
switch (jji)
case 1
% do something
case 2
% do something
case 3
% do something
case 4
% do something
otherwise
% handle other cases
end
case 2
switch (jji)
case 1
% do something
case 2
% do something
case 3
% do something
case 4
% do something
otherwise
% handle other cases
end
case 3
switch (jji)
case 1
% do something
case 2
% do something
case 3
% do something
case 4
% do something
otherwise
% handle other cases
end
case 4
switch (jji)
case 1
% do something
case 2
% do something
case 3
% do something
case 4
% do something
otherwise
% handle other cases
end
otherwise
% handle other cases
end
```
这样可以使代码更加简洁易懂,同时避免了重复的代码。
