What are the differences between iteration and recursion?
In computer programming, both iteration and recursion define a type of loop. With iteration, the loop makes use of the current instance of the function in which it appears. When we start a new iteration, the "state" of the previous iteration is carried forward to the new iteration but we cannot return to a previous state. With recursion we can return to a previous state because each recursion invokes a new instance of the function which automatically saves the state of the current instance. Whenever we return from an instance, the result of that instance can be passed back to the previous instance and be incorporated into its restored state.To demonstrate, consider the following iterative loop (in C++):for (unsigned i=0; i

How many types of recursion are there in c language?
Recursion in c language is a method where the function calls itself, within or outside the scope. Using Recursion, complicated problems can be divided into smaller parts so that solving them becomes more manageable. The recursion technique is available in Java, JavaScript, and C++.serves the same purpose. The type of Recursion in C • Direct Recursion • Indirect Recursion. Direct Recursion Recursion can call the function n-number of times. In the case of direct Recursion, the function calls itself inside the same position or in the local scope Direct Recursion problems are the Fibonacci series, a program to print 50 natural numbers. Indirect Recursion In the case of Indirect Recursion, a function X calls function Y, and function Y calls any function Z. Under certain conditions, function Z calls function A. In this case, function A is indirectly related to function Z. Indirect Recursion is also known as mutual Recursion, as more than one function runs a program. It is a two-step recursive function call process for making a recursive function call. Below mentioned are also type of Recursion: Tail Recursion No Tail/Head Recursion Linear Recursion Tree Recursion Tail Recursion A function is said to be tail recursion if it calls itself and also calls the last or the previous statement executed in the process. Head Recursion A function is said to be Head Recursion if it calls itself and also calls the first or the beginning statement executed in the process. Linear Recursion A function is said to be a linear recursive function if it makes a single call to itself each time the procedure executes itself and grows linearly depending on the size of the problem. Tree Recursion Tree Recursion is different from linear Recursion. Rather than making only one call to itself, that function makes more than one recursive call to the process within the recursive function. Following are the steps to solve the recursive problem in C: Step 1: Create a function and assign the work a part should do. Step 2: Select the subproblem and assume that the function already works on the problem. Step 3: Get the answer to the subproblem and use it to resolve the main issue. Step 4: The 90% of the problem defined is solved.

Write a program using recursion which should take two values and display 1st value raised to the power of second value.
What are the merits and demerits of recursion?
Ans: Merits of recursion are: Mathematical functions, such as Fibonacci series generation can be easily implemented using recursion as compared to iteration technique. Demerits of recursion are: Many programming languages do not support recursion; hence, recursive mathematical function is implemented using iterative methods. Even though mathematical functions can be easily implemented using recursion, it is always at the cost of execution time and memory space. The recursive programs take considerably more storage and take more time during processing.

Write a program to swap two numbers using function?

What is the algorithm n flowchart for calculating factorial of number using recursion?
A flowchart for factorial of number can be made using different software's. Microsoft Word is the most popular software for beginners to make simple flowcharts.In order to draw the flowchart write the number at the top of the paper and then draw two lines under it going slightly to the sides. Decide what two numbers can be multiplied to equal that number. Keep going until you can no longer get to smaller numbers.
What are the overheads in using recursion?
Variables that are passed to the function but your teacher wants to know where those variables are stored and why it can be a problem. It is your job to find out, its called learning.
Can you implement merge sort without using recursion?
Sure, recursion can always be substituted with using a stack.
What is the use of function in c?
