Method -1
#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
int i=2,n,e;
printf("Enter the limit\n");
scanf("%d",&n);
printf("Even nos upto %d\n",n);
for(i=2;i<=n;i=i+2)
         {
printf("%d\n",i);
         }
getch();
}

------------------------------------

Output

Enter the limit (Enter your choice)

8
