Instead of using multiple insertion operators,we can use only one operator right??? It will minimise the code right????

Answer 1

"Instead of using multiple insertion operators,we can use only one operator right???"

One << operator for every commit to the output stream. But if you are talking about the "cout" global object (as your question tag refers to), it's a matter of style and good practices. For example, it's best to associate all related pieces of the output to one cout as

int x = 20;
cout << "Who knows what's going to happen to programming world "
<< x << " years from now. But, almost all analysts have reached "
<< "to a general consensus on the matter of improved productivity."
<< endl;

Or

cout << "Who knows what's going to happen to programming world "
"20 years from now. But, almost all analysts have reached "
"to a general consensus on the matter of improved productivity.\n";

Versus, the unrelated facts and data as

cout << "function 1's return value is : " << f1() << endl;
cout << "function 2's return value is : " << f2() << endl;

Answer 2

Make sense. But i don't think it will make the code easier.

Answer 3

You are talking about C++?

Answer 4

I’m new to C, but this allows you to insert variables into your text stream

Answer 5

yes

Answer 6

cout<<"Hello"

Answer 7

return (0)
