While statement

The simplest of all the looping structures in is the while statement.
The basic format of while statement is
   while (test condition)
{
   body of the loop
}


include<stdio.h>
   void main( )
{
   int sum = 0;
   int n = 1;
   while (n<=10)
   {
   sum = sum + n*n;
   n = n+1;
   }
   print f ("sum = %d/n" ; sum);
}


Do-while
The general form of do while loop:
initialization:
   do{
        statement
        increment
       } while (condition);


include<stdio.h>
include<conio.h>
   void main( )
 {
   int i = 5;
   do { print f ("value of i = %d ", i);
   i++
   } while (i<5);
   print f ("/n current value of i =%d" , i);
   getch ( )
}

If and Else

Write a program that will read an integer number from the user.The program will examine whether it is an even number or odd number.

include <stdio.h>
include <conio.h>
   void main ( )
{
   clescr ( );
   int number 1, number 2, R;
   print f ("please enter two numbers");
   scan f ("%d%d",& number 1,& number 2);
   R = number 1%2;
   if (R= = 0)
   print f ("%d is an even number ", number 1);
   if (R= = 1)
   else
   print f ("%d is an odd number", number 1);
   print f ("n");
   getch ( );
}

   R = number 2%2;
   if (R= = 0);
   print f ("%d is an even number ". number 2);
   else
   print f (%d is an odd number ". number);
   print f ("/n");
   getch ( );
}

Program will input the total mark of a student.The program will then perform certain logical test and will print message depending on the test result.

include <stdio.h>
include <conio.h>
   void main ( );
{
   clrscr ( );
   int number ;
   print f ("Enter total mark of a student;");
   scan f ("%d", & number);
   if (number > = 330)
   if (number > = 450)
   if (number > = 600)
   print f ("First division");
   else
   print f ("Second division");
   else
   print f ("Third division");
   getch ( );
}

Assembler and Complier

The assembler of a computer system is a system software,supplied by the computer manufacturer which translates an assembly language program in to an equivalent machine language program of the computer.

A high level language program must be converted in to its equivalent machine language program before it can be executed on the computer.This translation is done with the help of a translation program,which is known as a compiler.

include <studio.h>
   main ( )
{
   int number;
   print f ("Enter an integer number/n");
   scan f ("d%", & number);
   if (number <100);
   print f ("your number is smaller than 100/n/n");
   else
   print f ("your number contains more than two light/n");
}


include <studio.h>
define PI 3.1416

   main ( )
{
   intr;
   float area;
   print f ("Enter the radius and hight of circle = ");
   scan f ("%d", & r );
   area = PI * r * r ;
   print f ("Area of cylinder = % .2 f ",area);
}

Arithmatic instruction

int a, b, sum;
Float average
a = 10;
b = 25;
c = a;
Sum = a+b+c;
        = 45;
Average = 45/3;
              = 15.00

Input Instruction:
  Scan f ( ) function is used to input integer.
Output Instruction:
  Print f ( ) function is used to print.
Variable declaration Instruction:
  int a;
  float b;
Control Instruction:
> Sequential control instruction.

> Selection control instruction.
> Looping control instruction.


include <stdio.h>
   main ( )
{
   int number
   Print f ("Enter an integer number/n");
   Scan f ("%d",& number);
   if (number<100)
   print f ("your number is smaller than 100/n/n");
   else
   Print f ("your number contains more than two digits/n");
   return 0;
}
