Question

Can someone plz explain me this it is of java and output is coming 126
why?? ​

Answer 1

Explanation:

Here m++ and n++ are postfix operators so they will increase m and n by 1 but after the calculation m++×n++ is performed so here 10×12=120.

Now the value of n has been increased by 1 by postfix plus so n=12+1=13.

and --n this is prefix subtraction so it will reduce the value of n by 1 before the calculation IS finished so n=13-1=12

then n/2=12/2=6

120+6=126

Answer 2

m++ and n++ are post increament operator hence,

this will used the previous value then increase the value by 1.

But --n is pre decreament. operator which first decreased the value by 1 then used for the value.

p=(m++*n++)+--n/2;

p=10*12+(12/2)

=>120+6

=126........ Output
