Question

solve with increment and decrement . a=7 , b=5 , c=2. Q= ++a,--a,b++,c++ please explain ​

Answer 1

Q = ++a

Assigns 8 .. This is because postfix first increments the value and then assigns it to the variable.

Q = --a

Assigns 7 .. because its previous value was 8 .. see first answer. It first decreses the value of the variable and then assigns it to the variable.

Q = b++

Assigns 5. because prefix first assigns the value and then increases it.

Q = c++

Assigns 2 . because prefix first assigns the value to the variable and then increases it.
