问题描述
在我的课堂上,我们要翻译C到MIPS。
In my class we are translating C to MIPS.
我们被要求翻译这个片段: A = A? B:C [0]
We are asked to translate this snippet:A = A ? B : C[0]
我相信我理解的三元运算符,但这里是什么想?如果不是A是一个布尔?在MIPS psented用1或0值,以便将它重新$ P $?
I believe I understand the ternary operator, but what is wanted here? Shouldn't A be a boolean? So would it be represented in MIPS with a 1 or 0 value?

推荐答案
这可能有助于第一翻译三元前pression假性code,例如:
It might help to translate the ternary expression to pseudo code first, e.g.:
if A != 0 // if A is non-zero, i.e. TRUE
A = B
else // otherwise A is zero, i.e. FALSE
A = C[0]
