1 New Member
in this question how it work .i am confuse about it.

Q. main()
{

int a=34,b=45;
a=a+b-(b=a);
printf("%d%d",a,b);
}
OUTPUT: a=45
b=34
according to the priority output should not be this .but machine is giving above
output.so i want to know that how does it work?

Hi,

a= 34 and b = 45 initially.
So a=a+b-(b=a); will be a = 34+45-(34)=45 as b=a=34

So new a=45 and b=34
