Hello World..!

Hello World..!

Hello guys..! Let's write a 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.

Program :
#include <stdio.h>
Void main()
{
      printf("Hello, World!"); // printf() => displays the statement inside the quotation.
 }


Output
Hello, World!
How its Works..
  • The #include <stdio.h> is a preprocessor command. This command tells compiler to include the contents of stdio.h (standard input and output) file in the program.
  • The stdio.h file contains functions such as scanf() and print() to take input and display output respectively.
  • If you use printf() 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, the printf() 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.

C Program To Reverse a Number

C Program To Reverse a Number Learn How To Reverse A Number in C Programming Language. It is important that we should know   How A For Loop Works  before getting further with this C Program Code. To Reverse the Digits of an Integer, we need to Extract every End Digit using Modulus Operator and then store it in a Sum variable. Then, keep on adding the other digits to the Sum variable. Example Reverse of 1234 = 4321 Method 1: Reverse an Integer with While Loop in C Programming 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 #include<stdio.h> #include<conio.h>   Void main ( ) {      int num , sum = 0 , rem , temp ;      printf ( "\nEnter a Number:\t" ) ;      scanf ( "%d" , & num ) ;      temp = num ;      while ( num > 0 )     ...
