This programme is for understanding the side effec.In the above program, the side effect has occurred. In sum1, first i is calculate first for that,i/2 is 5 and then fun(&i) is called that is return 41.so the result is 46.

In sum2, first fun(&j) is called, that’s return 41 and update the j is 14.so j/2 is 7.result is 48.
