Nettet24. mai 2024 · What will be the output of following program? The answer is option (2). Explanation: Because here c++ is post increment and so it takes value as 4 then it will increment. ++c is pre-increment so it increment first and value 6 is assigned to c, .~ means -6-1=-7 then c= (4-7)=-3. NettetA quick summary of terminology. The expression b++ invokes the post-increment operation. C has several variations: b--post-decrement++b pre-increment--b pre-decrement NettetThe output will be 4. Here is how the logic works on your case: Given : a = 3 b = 2 Then : b = a++ which means take a value to b and then increment the a value. so b value is same as a (before the increment), so with that statement, their value become: b = 3 (same as a before increment) a = 4 (the value change because we got increment) Then evaluate … cfo southern company
