In the realm of programming, the task of identifying and handling duplicate characters within a string is a common challenge faced by many developers. In this article, we will delve into the intricacies of dealing with duplicate characters in a string using the C programming language.

Finding Duplicate Characters

When working with strings in C, the first step in dealing with duplicate characters is to identify their presence. One efficient approach is to traverse the string character by character, keeping track of the duplicates encountered.

Methodology

To implement this, we can use an array to store the count of each character present in the string. By iterating through the string and incrementing the corresponding count in the array, we can easily identify the duplicates.
