# Introduction Swapping two numbers means interchanging their values. In this lab, we will learn how to swap two numbers in C language using different methods such as using a temporary variable, addition and subtraction, bitwise operators, multiplication and division. > Note: You need to create the file `~/project/main.c` yourself to practice coding and learn how to compile and run it using gcc. ```bash cd ~/project # create main.c touch main.c # compile main.c gcc main.c -o main # run main ./main ```
