WebOct 22, 2010 · int? x = 100; - means create a nullable type int and set it's value to 100. int y = x ?? -1; - I think means if x is not null then set y = x otherwise if x is null then set y = -1. Don't see ?? very often. So since x is not null y will equal 100. That's what I think; might not be true. Lets see what others say. Web1 You can read x++ as, "Use x, then increment it by 1." And inversely with ++x, "Increment x by one, then use x." So when you have this snippet, using the pre-increment operator: ? 1 2 x = 10; y = ++x; You are incrementing x by one and then assigning its value to y. So x will equal 11 and y will also equal 11.

Sorry if it's not … WebStep 1: int x=4, y, z; here variable x, y, z are declared as an integer type and variable x is initialized to 4. Step 2: y = --x; becomes y = 3; because (--x) is pre-decrement operator. Step 3: z = x--; becomes z = 3;. In the next step variable x becomes 2, because (x--) is post-decrement operator. greyhound scenicruiser rv
