Share it Please
this program will print all the Even numbers under the number entered by user when this program is executed.In this program we have b=0 as a first Even number.then after printing first number it will increase the value of 'b' by 2 and new value will be 2 which is also a Even number and like this, program will run till condition becomes false in for loop.

Program:

#include<stdio.h>
#include<conio.h>
main()
{
      int a,b;
      clrscr();
      printf("Enter Number: ");
      scanf("%d",&b);
      printf("\n");
      for(a=0;a<=b;a+=2)
      {
           printf("%d,",a);
      }
      getch();
}
