C++ String Practice Problems

This repository contains a collection of C++ programs designed to tackle various string manipulation challenges. The programs use a combination of algorithms, including recursion, to solve problems involving substrings, character manipulation, and other string operations.

Programs Included

1. Count_Hi.cpp

Counts the number of occurrences of the substring "hi" in a given string.

2. Count_Vowel.cpp

Counts the number of vowels in a given string.

3. IsAnagram_Checker.cpp

Checks if two given strings are anagrams of each other.

4. IsPangram_Checker.cpp

Checks if a given string is a pangram (contains every letter of the alphabet at least once).

5. Length_of_String_usingPointers.cpp

Calculates the length of a string using pointers.

6. Lexicographical_order.cpp

Sorts a list of strings in lexicographical order.

7. Remove_X.cpp

Removes all occurrences of the character 'x' from a given string.

8. Remove_leading0.cpp

Removes leading zeros from a given string representing a number.

9. Replace_XY.cpp

Replaces all occurrences of the substring "xy" with another string in the given string.

10. Replace_pi.cpp

Replaces all occurrences of the substring "pi" with "3.14" in a given string.

11. Reverse_String_PalindromeCheck.cpp

Reverses a given string and checks if it is a palindrome.

12. Sandwich_String.cpp

Extracts and prints the substring between two specified characters in a given string.

13. move_all_x.cpp

Moves all occurrences of the character 'x' to the end of the string.

Key Features

• Recursion: Many programs in this repository utilize recursion to simplify and solve complex string manipulation problems.
• Substrings and Characters: The programs cover a variety of string operations, including substring extraction, character replacement, and more.
