Write a program to print "Hello World" in c
How "Hello, World!" program works?
- The
#includeis a preprocessor command that tells the compiler to include the contents ofstdio.h(standard input and output) file in the program. - The
stdio.hfile contains functions such asscanf()andprintf()to take input and display output respectively. - If you use the
printf()function without writing#include <stdio.h>, the program will not compile. - The execution of a C program starts from the
main()function. printf()is a library function to send formatted output to the screen. In this program,printf()displays Hello, World! text on the screen.
