C programming
The document discusses the components of a C programming language program including constants, variables, keywords, instructions, and comments. It provides examples of simple C programs - one that prints "Hello World" and another that checks if a user-input number is even or odd. The even/odd program uses an if statement and modulo operator to check the remainder when dividing the number by 2 and prints the corresponding output.

- 14. /* Filename: hello.c Author:BT 414 Date written: 17/10/2011 Description: This program prints the greeting “Hello, World!” */ #include <stdio.h> int main ( void ) { printf ( “Hello, World!n” ) ; return 0 ; }
- 15. #include <stdio.h> int main() { intnum; printf("Enter a number you want to check.n”); scanf("%d",&num); if((num%2)==0) //checking whether remainder is 0 or not. printf("%d is even.",num); else printf("%d is odd.",num); return 0; } Output 1 Enter a number you want to check. 25 25 is odd. Output 2 Enter a number you want to check. 2 2 is even.
