Parts of C quotHello, World!quot Program. Here is the breakdown of the above code and all elements used in the above code . 1. Comment Section First C programComments are used to specify a textual line that is not supposed to be executed when we compile the code. The compiler ignores the line, and proceeds to the next line.

Explanation The include ltiostreamgt line includes the necessary header. The main function is the entry point of the program. stdcout ltlt quotHello, World!quot ltlt stdendl outputs quotHello, World!quot to the console. return 0 indicates successful program execution. This simple program demonstrates the basic structure of a C program and how to use the stdcout stream to output text to the

g hello_world.cpp -o hello_world IDE Most IDEs have a quotBuildquot option which automatically compiles your code. Executing Your Program. After compiling your program, you can run it.
