Increment operator (++): It increments the value by 1. There are two variations of increment operators. Post-Increment: First use the variable after that increment the value of a variable. Pre-Increment: It is the opposite of post-increment. In this first increment, the value and after that used the value of a variable. The evaluation of these operations start from right to left. Pre increment: ++i, it increment the value and assign to i and now value is 3. Post increment: i++, it increment the value but doesn't assign to i so value still 3 That's why answer is 6.

Learn concepts of increment and decrement without know it u cannot calculate . int a= 5,b; b= ++a + ++a + a++ + a its very confusing so without knowing concepts you can not solve

i++ assigns i the value of 2, then i increments to 3 ++i increments the value of i to 4 then 2+4=6
