# Introduction Exponential calculation is a very common requirement in many mathematical applications. In C programming, we can calculate exponentials using the `pow()` function. However, sometimes we might need to find the exponential of a number manually without using the `pow()` function. In this lab, we will go through the steps to find the exponential of a number without using the `pow()` function in C programming. > 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 ```
