Learn about How to Write C Program Without Header File in the below code example. Also refer the comments in the code snippet to get a detailed view about what’s actually happening.

In general, we include at least one header file stdio.h in every C program. The printf and scanf functions that we use frequently in our software are specified in the stdio.h header file. The inclusion of stdio.h serves to add the definition of these functions to our program. Using the C preprocessor, we can extract the printf function definition from the header file and utilize it directly in our program.
