what does this mean

[sub_slack]

in some program i saw this line

result += array[i] ? array[i] : 90;

i was wonderind what does this mean. hope you can help.

[coolman0stress]

it's the same as:

if(array[i])
       result+=array[i];
else
       result+=90;

Instead of doing all that C has the tertiary construct (three involved elements), (evaluate)?(if true): (if false).

Hope this helps

[sub_slack]

yes, thanks , it helps, but i'm still a little confused ,how should i understand

if(array[i])

that means if value of array[i] is true ,right?

[coolman0stress]

Pretty much, just checking wether there is anything at array[i]. With "anything" meaning a value other than 0 (or if there is no element at that index)(which would be false), all other values are true(basically there is an element there)(so not only 1).

[sub_slack]

ok, thanks, i understand it now

>>(or if there is no element at that index)(which would be false)<<
There is always a value at that location (index), even if the value of i exceeds the array bounds.

Just conditional operator man. You can refer tutorials.
