adding space

Code:

---

#include <iostream>
using namespace std;

int main()
{
        int a,b,c;
        cout<<"enter a number";
        cin>>a;
        cout<<"enter a number";
        cin>>b;
        cout<<"enter a number";
        cin>>c;
        cout<<a <<a*a <<endl;
        cout<<b <<b*b <<endl;
        cout<<c <<c*c <<endl;
        return 0;
}

how do i add a space between the number and the squared number??? thank you

Code:

---

cout << a << " " << a*a << endl;

---

i would use single quotes:

cout<<a<<' '<<a*a;

Using the double quotes is better, because you need them anyways if you're going to use a two or more character delimiter.

you can use single quotes for up to and including two characters...

Except for the fact that when you cout a 2-character constant surrounded by single quotes, it treats it like an integer.

Code:

---

#include <iostream>

int main( void )
{
  std::cout<<"a"<<', '<<"b"<<std::endl; // Delimeter is a comma and a space
}

This code outputs a11296b. 11296 is the value of (','<<8) | '&nbsp;'.

oh really? I didn't know that... i only use it for escape sequences and spaces, etc.

But an escape sequence is only one character. It just looks like two. ;)
