gives error
"error C2105: '++' needs l-value"
because it parses above expression in "((i++)++)+i), so in
2nd unary operator it searches for l-value.
If we modify above pgm into following way:-
void main()
{
int i=5;
printf("%d",((i++)+(++i)));
}
it will give answer 12.
because once last pre-unary increment operator is operated,
i is incremented to 6 and 6+6 = 12.
if we put one more print for i's value, it will give i =7.
because first post-increment operator is operated after
first printf statement as follows.
void main()
{
int i=5;
printf("%d",((i++)+(++i)));
printf("%d\n",i); // ===> i =7
}

Write a function stroverlap that takes (at least) two strings, and concatenates them, but does not duplicate any overlap. You only need to worry about overlaps between the end of the first string and the beginning of the second string. Examples: batman, manonthemoon = batmanonthemoon batmmamaman, mamamanonthemoon = batmmamamanonthemoon bat, man = batman batman, batman = batman batman, menonthemoon = batmanmenonthemoon
