C Program to Convert Number to Words (0 to 99999)

Converting a number to words means printing its English name: 4562 becomes four thousand five hundred sixty two. This is useful in invoice generation, banking applications, and cheque printing.

C Program to Encrypt and Decrypt a Password (XOR Cipher)

This classic exercise asks you to encrypt and decrypt a password in C. The right teaching tool for it is the XOR cipher: XOR each character with a key byte, and XOR-ing a second time with the same key restores the original — one function does both directions. This page gives you a tested implementation …

Anagram Program in C – Check if Two Strings are Anagrams

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 …

Delete a File in C – remove() with Error Handling

To delete a file in C, call the standard library function remove() from <stdio.h>: it takes the file name as a string and returns 0 on success. That one line is portable across Linux, macOS, and Windows — no operating-system headers needed. What separates a toy example from production-quality code is what happens when deletion …
