CBCS C Program to Print a Sentence
Dear readers, here you will learn to write simple C program to display “Hello, World!” on the screen. Since, it’s a very simple program, it is often used to illustrate the syntax of a programming language.Yeah ! Obviously you can write any sentence instead of “Hello, World!” .
To understand this example, you should have the knowledge of following C programming topics:
- C Programming Input Output (I/O): printf() and scanf()
# C Program to Display “Hello, World!”
#include <stdio.h>
int main(void)
{
// printf() displays the string inside quotation
printf("Hello, World!");
return 0;
}
Output
Hello, World!
# How “Hello, World!” program works?
- The
#include <stdio.h>is a preprocessor command. This command tells compiler to include the contents ofstdio.h(standard input and output) file in the program.
Thestdio.hfile contains functions such asscanf()andprint()to take input and display output respectively.
If you useprintf()function without writing#include <stdio.h>, the program will not be compiled. - The execution of a C program starts from the
main()function. - The
printf()is a library function to send formatted output to the screen. In this program, theprintf()displays Hello, World! text on the screen. - The
return 0;statement is the “Exit status” of the program. In simple terms, program ends with this statement.
