You must master copying, concatenating, and comparing strings safely without overflowing memory boundaries. 4. Basic Algorithmic Logic
The exam isn’t just about coding; it’s about . Unlike the group-oriented "Rush" projects or peer-corrected daily exercises, Exam 01 is a solitary experience. Students are stripped of their greatest resource—the internet and their peers—and left only with a terminal and their own memory.

Your code is graded automatically by Moulinette , 42’s automated grading machine. Moulinette is binary: your code is either 100% correct or it is a 0. There is no partial credit. c piscine exam 01
Always draw out the memory locations on your whiteboard if you are stuck. Remember that a pointer holds the address , and *ptr accesses the value at that address. C. String Manipulation
What happens if the input pointer is NULL ? What happens if an integer is negative or 0 ? What if the string is empty ( "" )?
int x = 5; // integer variable char c = 'A'; // character variable float pi = 3.14; // floating point variable Your code is graded automatically by Moulinette ,
Compile using flags to catch warnings early: gcc -Wall -Wextra -Werror ft_swap.c main.c
If you are currently preparing for your upcoming exam, let me know:
The exam takes place in a "locked down" environment. You log in using a special "exam" account and use the command to start. Time Limit: Typically 4 hours. working with while loops
Calculating factorials using loops or recursive call stacks.
If your code is failing the grading machine but looks correct to your eyes, stop typing. Use the scrap paper provided in the cluster. Draw memory boxes for your variables, write down their addresses, and manually trace through your loops line by line. This is the fastest way to find off-by-one errors and pointer routing mistakes. 3. Master the ASCII Table
Writing functions to print strings or numbers using write , working with while loops, and simple if-else conditions.
