C Program to print prime factors


Write a C Program to print prime factors using Recursion and Iteration. Here’s simple Program to print prime factors using Recursion and Iteration in C Programming Language.


Recursion : :


  • Recursion is the process of repeating items in a self-similar way. In programming languages, if a program allows you to call a function inside the same function, then it is called a recursive call of the function.
  • The C programming language supports recursion, i.e., a function to call itself. But while using recursion, programmers need to be careful to define an exit condition from the function, otherwise it will go into an infinite loop.
  • Recursive functions are very useful to solve many mathematical problems, such as calculating the factorial of a number, generating Fibonacci series, etc.

Iteration : :


  • Iteration, in the context of computer programming, is a process wherein a set of instructions or structures are repeated in a sequence a specified number of times or until a condition is met.
  • When the first set of instructions is executed again, it is called an iteration. When a sequence of instructions is executed in a repeated manner, it is called a loop.

Example : :

for (int i=0;i<n;i++)
{
\\ statements;
}


Below is the source code for C Program to print prime factors using Recursion and Iteration which is successfully compiled and run on Windows System to produce desired output as shown below :
