Many brilliant coders fail Exam 01 because of simple, avoidable mistakes. Moulinette does not care about good intentions; it only cares about binary perfection. 1. Missing the Forbidden Functions Rule
When you submit a project using the vogsphere git repository, the system grades it within minutes.
Arrays are collections of elements of the same data type stored in contiguous memory locations.
This guide covers topics typically tested in a C "Piscine" (intensive bootcamp-style course) Exam 01: C fundamentals, data types, operators, control flow, functions, pointers, arrays, strings, memory management, and basic debugging. Use this as a study reference and quick reference sheet. c piscine exam 01
Characters are just numbers under the hood. You must know how to manipulate them mathematically: Lowercase characters range from 'a' (97) to 'z' (122). Uppercase characters range from 'A' (65) to 'Z' (90). Numeric digits range from '0' (48) to '9' (57).
Read the allowed functions section. If the assignment allows the write function, and you accidentally include or use printf , you will fail instantly. Note the directory structure and naming conventions perfectly. Step 2: Write Your Main Function Locally
| Feature | Description | |---------|-------------| | | Must pass (no forbidden functions, proper indentation) | | Memory leaks | Detected by Moulinette (strict malloc / free balance) | | Segfault protection | Null checks, bound checks required | | Static vs dynamic | Must allocate exactly as required (e.g., ft_strdup uses malloc ) | | Prototype matching | Exact function signature | | Hidden tests | Many edge cases tested (empty string, negative numbers, min/max int) | Many brilliant coders fail Exam 01 because of
You must understand how memory stores information. Expect to work heavily with: char : 1 byte of memory, tracking ASCII characters. int : 4 bytes of memory, tracking whole numbers. Signed vs. unsigned variables. Control Flow
To succeed in Exam 01, you should be comfortable with everything from the modules:
I can provide targeted code snippets and logic breakdowns to prepare you for the system. Share public link Missing the Forbidden Functions Rule When you submit
Calculating factorials using loops or recursive call stacks.
Exam 01 serves as a bridge between the absolute basics of programming and slightly more advanced C concepts. While the exact exercises vary, you can consistently expect to see problems related to the following skill sets: 1. Basic C Programming (Pointers, Arrays, and Strings)
