1. C code - Hello world

Problem: Write a c program which show the line "Hello World!!!"

C program:




Output: Hello World!!!

Description: For this problem only one line is needed for output. Due to line-5  we get the output Hello World!!! .

Here we use a function name printf(), the definition of this function defined into a file name stdio.h that's why we include it at the beginning of program (line-1). Other lines are basic structure of a C program which will be describe later.
