The above-given type of recursion is explained below: There are two types of recursion in C programming that are given below: 1. In the above-given example to calculate the factorial of a number below is the scenario for memory allocation. What is the base condition is reached, the memory allocated to the function gets destroyed and pointer returns to the calling function? this process is repeated then the first calling function and at last, the stack memory gets empty. When a recursive function is called memory is allocated to it on the top of the memory that has been allocated to the calling function with all the different copy of local variables are created for each call to the function. Memory Allocation of Recursive FunctionД®ach call to a function in c language results in memory allocation on the top of a stack. Thus result in main function stores 24 and prints that on output. Similarly, it will return 3*fun(2) is called and this continues up to 2*fun(1) is called and where it meets the base condition and returns 1 then calling function returns 2*1 then,3*2*1 and from the first call 4*3*2*1 is returned. When the main function calls fun(4) then first the exit condition (4=1) is checked then 4*fun(3) is called. The above-given example is of finding the factorial of a number. Printf('%d',result) //prints the output result. The value returned is multiplied with the argument passed in calling function. Return n*fun(n-1) //function is called with n-1 as it's argument. If(n=1) return 1 //exit or base condition which gives an idea when to exit this loop. Now we will be going to see the examples ofВ Recursive Function in C Incase base condition or exit condition is not specified in the function then recursive calls to the function can lead to an infinite loop. This way recursive calls are made to the function delete reaches the first function and the whole stack memory gets cleared and output is returned. similarly, the new value gets calculated in the calling function and IT returns to the super calling function. The memory allocated to that function gets cleared. When the base condition returns true, the particular value passed to the calling function. When compiler detects a call to another function it immediately allocates new memory on the top of the stack where a different copy of the same local variables and the function gets created. The condition for exit is checked if it fulfills. All the operations present in the function are performed using that memory. A recursive function is called with an argument passed into it say n, memory in the stack is allocated to the local variables as well as the functions. Recursive functions are the way to implement the equation in C programming language.

Just imagine if you have to write the same program 100 times, you will be seriously irritated plus it will occupy a lot more space. It needs a set of instructions, loops, and boom! our work is now less and effective. The recursion technique is one of those things. This can prevent our program from being complicated and thus reducing the run-time which makes our program looks better and efficient. With the use of these features known as recursion, we can use a certain part of our choice n number of times without writing it again. C provides us some of the features where we can reuse some of the parts of the program as required without writing those things again and again.
