推荐答案

答案是m = 3.



从顶部开始向前走。 a和b设置为2.c设置为4.



a是否大于b（2大于2）？没有。转移到其他地方。



c不等于零（3不等于0）？是。按照当时的说法。



m设置为3.



如果代码标签有点不同它可能更容易遵循if / then / else流程。

The answer is m = 3.

Start at the top and work your way down. a and b are set to 2. c is set to 4.

Is a is bigger than b (2 bigger than 2)? No. move to the else.

Is c not equal to zero (3 not equal to 0)? Yes. Follow the then.

m is set to 3.

If the code was tabbed a bit differently it might be easier to follow the if/then/else flows.
