what '?' in c++? 7 answers

i confused next codes , seek understand mean.

if( (root->left == null) || (root->right == null) ) { node *temp = root->left ? root->left : root->right; }

it means if root->left ==null temp = root->left? else temp = root->right?

you not right, u idea. conditional operator takes 3 operands.

var = status ? expression1 : expression2

is equivalent

if( status ) var = expression1 else var = expression2

in case means

if root->left != null temp = root->left, else temp = root->right

instead of

if root->left ==null temp = root->left, else temp = root->right
