In what order does evaluation of post-increment operator happen?

Question

Given

std::vector objects;
CMyClass list[MAX_OBJECT_COUNT];

Is it wise to do this?

for(unsigned int i = 0;          


        

Answer 1

As it has been said already, post-incrementing a variable in the same expression it is used yields undefined behaviour. However, if you wish to keep the compact form, you could introduce a sequence point and go for

for(unsigned int i = 0; i < objects.size(); list[i] = objects.at(i), i++);
