Question

Given the following recursive code. Point out the possible errors in the code. 

//num is a positive integer

int fac(int num) 

{ 

if (num≤1) return 1; 

else { 

return num*fac(num+1); 

}

Answer 1

There is no misplaced else.Two round brackets are missing for the return statements.it should have been

return (1) 

return (num* fac (num-1)) 

Note :- it is not (num+1) but (num-1)
