About this app

C Programming Code is a library of 82 complete, working C programs for students and beginners. Every program is written in standard C (C17), compiles without warnings, and comes with a real sample run and a short explanation of how it works. Diagrams show what happens inside sorting, searching, matrix and pointer programs.

What the app covers

• Basics: how to compile and run a program, Hello World, reading input safely with scanf and fgets, arithmetic operators, swapping, sizes and ranges of data types, character codes
• Conditions: even or odd, vowel or consonant, leap years, largest of three numbers, grade calculator, roots of a quadratic equation
• Loops and Numbers: sum and average, multiplication table, sum of digits, reverse and palindrome numbers, factorial, Fibonacci series, prime check, Sieve of Eratosthenes, Armstrong and perfect numbers, GCD and LCM, nCr and nPr, fast power
• Patterns: star and number triangles, pyramid, diamond, hollow square, Floyd's triangle, Pascal's triangle
• Number Systems: decimal to binary, octal and hexadecimal and back, bitwise operators
• Arrays: sum and average, largest and smallest element, reverse, insert and delete, linear search, binary search, bubble sort, selection sort, insertion sort, merging sorted arrays, frequency count, removing duplicates
• Matrices: addition and subtraction, multiplication, transpose, 2 × 2 and 3 × 3 determinants
• Strings: length, reverse, palindrome, vowel count, case conversion, word count, concatenate, compare and copy without the library, anagram check, removing characters, string to integer
• Pointers and Functions: pointer basics, swapping with pointers, arrays and pointers, dynamic arrays with malloc and realloc, function pointers and qsort, recursion, Tower of Hanoi
• Structures and Files: student records, complex numbers, writing and reading a text file, counting lines and words in a file, copying a file
• Simple Projects: calculator, temperature converter, bank account menu, number guessing game, tic-tac-toe

Each program page has
• the full program, ready to copy, compile and run
• a sample run captured from the real program, with the typed input highlighted
• a clear "how it works" explanation, with tables and diagrams where they help
• notes on common mistakes: integer overflow, buffer overflows, unsafe input and undefined behaviour
• links to related programs

Who it is for
Students learning C at school or university, beginners who learn best from examples, and anyone preparing for programming lab exams or practical tests. It is the example-program companion to the C Programming tutorial app.

Features
• Works offline: no internet connection needed
• Explanations available in 8 languages: English, Español, Português, Français, Deutsch, العربية, हिन्दी and Bahasa Indonesia
• Search across all programs
• Dark mode
• Clean layout for phones and tablets
• No sign-in

The programs are original and were tested with a C17 compiler. This app is an independent study aid; it is not affiliated with any compiler vendor or standards body.
