LOOP STATEMENTS

1. This program generate a series from 1 to 10 using while loop

#include<conio.h>
#include<stdio.h>

void main()
{
  int i=1;
  while(i<=10)
  {
  printf("\n%d",i);
  i++;
  }
getch();
}


/*The output of the above program is

*/

2. This program generate a series from 1 to 10 using do..while loop

3.This program generate a series from 1 to 10 using for loop

#include<conio.h>
#include<stdio.h>

void main()
{
  int i;
  for(i=1;i<=10;i++)
  {

4.This program generate a table of a given input number

#include<conio.h>
#include<stdio.h>

void main()
{
  int num,result,i=1;
  printf("\nEnter a number to generate the table : ");
  scanf("%d",&num);
  printf("\nThe table of %d is given below",num);
  while(i<=10)
  {
  result=num*i;
  printf("\n\t %d * %d = %d",num,i,result);
  i++;
  }
getch();
}


/*The output of the above program is
**
Enter a number to generate the table : 3
The table of 3 is given below
    3 * 1 = 3
    3 * 2 = 6
    3 * 3 = 9
    3 * 4 = 12
    3 * 5 = 15
    3 * 6 = 18
    3 * 7 = 21
    3 * 8 = 24
    3 * 9 = 27
    3 * 10 = 30
