Question

Assume n = 10; what will be result of n++ and --n;?

Answer 1

11 and 9 respectively.

the notations like n++ and ++n are used in coding

both n++ and ++n stand for n=n+1 but there is small difference.

if we assume a=10 and n=10 then a<++n is true but a<n++ is false.

for a<++n first n value gets increment by 1 and becomes 11 then the condition is checked.

for a<n++ first the condition is checked and becomes false then n is incremented by 1 and becomes 11.

- -n and n- - also explained in the same way but - - is decrement operator w3here as ++ is increment operator.
