C Program To Find Permutations of String

C Program To Find Permutations of String using Recursion

Learn How To Find Permutations of String in C Programming. This C Program To Permute all letters of a string without Recursion makes use of Pointers. The C program prints all permutations of the string without duplicates. You can also modify the code to print permutations of a string with duplicates.

What is Permutation of a String?

String Permutations is a way to uniquely arrange all the letters of the string. These permutations may or may not include repetitions which can be modified in your program code.

Recursion is the best possible way of finding permutations of the string as it helps to build a clean code and also eases the debugging.
