C - PROGRAM :- LESSON 02

DECLARATION STATEMENT

1. #include <stdio.h>
/*this is a library in the C compiler which is the software where you run the programs.*/
2. int main()
/*this is the main function of the program, the body of the program will be inside this function.*/

3. { int x, y, z;
/*this is the declaration of variables of type integer*/

4.printf("Enter two numbers to multiply(enter a space between numbers): );
/*printf('''); is a function in the compiler which outputs what's in between the " " to the monitor*/

5. scanf("%d%d", &x, &y);
/*scanf(""); is another function except this one inputs what's in between the " " and stores it into the variable for this example x and y*/

6. z = x * y;
/*the = sign is an assignment to the left, so it assigns the product of x and y to the variable z*/

7. printf("The product is : %d", z);

8. return 0;
/*this code is what tells the compiler that you are terminating the program it returns 0 to the operating system*/

9. }
/* this is the closing bracket just like in a math funtion*/

OVERVIEW OF C

Elements of C language
C is an efficient and portable general purpose programming language. It was developed in the year 1972 at Bell Telephone Laboratories (AT&T) by Dennis Ritchie. The name C was taken from the second letter of the earlier version BCPL Basic Combined Programming Language developed by Ken Thompson of Bell Laboratories.

Until 1978 C was restricted within Bell laboratories. But after publication of definite description of the language by Brain Kernighan and Ritchie the language began to promote.

Features of C-language
(i) It is a flexible high level structured programming language.
(ii) It includes the features of low level language like assembly language.
(iii) It is portable. A program written for one type of computer can be used in any
other type.
(iv) It is much faster and efficient.
(v) It has an ability to extend itself.
(vi) It has a number of built-in functions, which makes the programming task
simple.

MY FIRST PROGRAM IN "C"

PROGRAM-01

AIM:-To write a simple program in "C" to explain the functions of 'printf & getchar' commands

PROGRAM:

/* My First Program in 'C'*/

#include <stdio.h>

main()
{

printf("HELLO WORLD");

getchar();

}
