Question

a c program for printing output as hello world​

Answer 1

Answer:

#include <stdio. ...

int main() – Here main() is the function name and int is the return type of this function. ...

printf("Hello World"); – This function displays the content within double quotes as it is on the screen.

Answer 2

The code of the program would be:

/* C Program for printing hello world as the output */

#include <stdio.h> // Header file

int main() // main function

{

printf("hello world");

return 0;

}

• Here We have started with including the header file stdio.h which is Standard Input Output Header file.
• Any program starts execution from the main function, which here takes no arguments and returns a value of type int.
• So we have written int main()
• Then We have used printf which prints text as Output. Notice that we have used ; which is the statement terminator.
• Next we have written return 0 that is if the program gets executed property, It will show exit code as 0 otherwise some other integer.
• Also // and /* are used to write comments in the program, which are ignored by the compiler, and helps the reader understand the functionality of the code.
