Now is the time for all good men to come to
the aid of their country. This is just a
regular paragraph.

The quick brown fox jumped over the lazy
dog‘s back.

This is a blockquote.

This is the second paragraph in the blockquote.

I get 10 times more traffic from Google than from
Yahoo or MSN.

I strongly recommend against using any <blink> tags. I wish SmartyPants used named entities like — instead of decimal-encoded entites like —.

If you want your page to validate under Xhtml 1.0 Strict,

you‘ve got to put paragraph tags in your blockquotes:

#include <iostream>
#include <stdio.h>
#include <string.h>

using namespace std;

int main()
{
    int a,b;
    scanf("%d%d",&a,&b);
    printf("%d\n",a+b);
    return 0;
}
