Solving problems through iteration is very complex but in recursion the same problem is solved very easily. Advantages and Disadvantages of Recursion. If method A calls method B, method B calls method C, and method C calls method A we call the methods A, B and C indirectly recursive or mutually recursive. Some problems are inherently recursive like tree traversals, Tower of Hanoi, etc. We have covered all the basic of C, C++, C#, JAVA, VB.NET, ASP.NET, etc..., programming language with easy examples and their descriptions. Now we will be going to see the examples of Recursive Function in C Code: #include int fun(int n) { if(n==1) return 1 ; //exit or base condition which gives an idea when to exit this loop. In general, with languages like C and C++, the iterative code will â¦ Disadvantages of Recursion. The first one is called direct recursion and another one is called indirect recursion. More: In recursion, the recursive function calls itself over and over again and keeps on going until an end condition is met. Indirect recursion occurs when a method invokes another method, eventually resulting in the original method being invoked again. Recursive solution is always logical and it is very difficult to trace. You call the function only once and it keeps calling itself till the end result is not received. Function funct() in turn calls itself inside its definition. You call the function only once and till the end result, it keeps calling itself. » Articles Disadvantages of using recursion » C Enter the number of natural numbers to be added: (10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 + sum(0)), (10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 + 0).
