The expressions and their output as seen on Codeblocks 12.11 are -
int i = 1, x;
x = i++ + i++ + ++i ++i
output : x = 7 and i = 5;
But for the following -
int i = 1, x;
x = ++i ++i + i++ + i++
output : x = 12 and i = 5;
Can anyone be kind enough to help me know how to solve these types of expressions correctly ?
Thanks in advance.

Yes, you rewrite them so they no longer exhibit undefined behaviour.
And read this -> Post and Pre Increment
Learn that such code has no value because there is no way to figure out what any given compiler is going to do with it (because it's UNDEFINED BEHAVIOUR).
If your tutor has trouble with this, just send them over here for some re-education.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
