print + if number is positive

[xantavis]

How do you make a positive number, that, if you print it out, also has a + infront of it, for example:

int a = 4;
cout << a;

prints "+4"

[Kmitska]

Well... you might do it with if else:

if ( a >= 0 ) {
cout << "+" << a << endl;
}else {
cout  << a << endl;
}

Isnt there another way?

Include <iomanip> and do

int a = 4;
cout << showpos << a;
