Welcome to the Programming with C wiki - Paul-Babs/Programming-with-C GitHub Wiki

C Standard library functions or simply C Library functions are inbuilt functions in C programming.

The prototype and data definitions of these functions are present in their respective header files. To use these functions we need to include the header file in our program which is #include <stdio.h>

If you try to use printf() without including the stdio.h header file, you will get an error. C is a powerful general-purpose programming language. It can be used to develop software like operating systems, databases, compilers, and so on. C programming is an excellent language to learn to program for beginners. Here, our C project consist of various codes like How to add two integer's, how to multiply two floating point numbers, How to swap two numbers, how to find a length of a string and so on.
