Give the logic for this #include<stdio.h> #include<conio.h> void main() { clrscr..

Answer / suman halder

++a is an unary expression which signifies pre-increment operation...so ,pre-increment will be evaluated before the binary operation takes place..
b=++a + ++a;
here,a will be incremented twice and then binary operation is performed...
so,
b=12+12 which produces 24...
