# Introduction In this lab, we will write a C program to check if the input number is an integer or a float. We will be using basic string manipulation techniques to check for the presence of a decimal point in the user input. > 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 ```
