Reversing a string in C means rearranging its characters so the last character becomes the first and vice versa: “Hello” becomes “olleH”. The standard technique is the two-pointer swap — place one pointer at the start and one at the end, swap the characters they point to, then move the pointers toward each other until …
C Strings:Write a C program to Encryption and Decryption of password.In this program we encrypt the given string by subtracting the hex value from it. Password encryption is required for the security reason, You can use so many functions like hash or other keys to encrypt. Read more about C Programming Language . and read …
An anagram is a word or phrase formed by rearranging all the characters of another. In C, the standard way to check if two strings are anagrams is to count character frequencies: if both strings have exactly the same character counts, they are anagrams — regardless of order. This page shows a complete anagram program …

Write a C Program to demonstrate strspn function.The strspn() function returns the index of the first character in string1 that doesn’t match any character in string2. If all the characters of the string2 matched with the string1, strspn returns the length of the string1. Read more about C Programming Language . /************************************************************ You can use …
Replacing a substring means finding every occurrence of one piece of text inside a string and swapping it for another — for example, turning “the cat sat on the mat” into “the cog sog on the mog” by replacing “at” with “og”. C has no built-in function for this (unlike Python’s str.replace()), so it’s a …
