Answer Posted / lakshmi
first it checkes the main function i.e., fn()
int fn(7)
if(7==1||v==0) : this is false so the complier executes
the next if condition
if(7%2==0) : This is false so it executes the else
instruction
return fn(6)+3; :here we are again calling the fn
function .So the loop executes till the 7 becomes 1
After this the first if condition is true so it rerurns 1
to the function fn(1)+3
so the answer is 1.
