Printing % character attached to floating number-CodePudding

So Let's say I am overloading OS operator and I want to have some sort of table of values divided into columns looking like this:

┌───────────────┬──────────────────────┬─────────────┬──────────────┐
│      X        │         Y.           │ Z.          │ value        │
├───────────────┼──────────────────────┼─────────────┼──────────────┤

and below I am printing those Values using stream:

<< std::setw(13) << std::noshowpoint << value << "%" << "|" << endl;

how can I do this so the output of let's say value equal to 5 will be printed as 5%

I tried to use to_string method but results were overriding noshowpoint operator.

CodePudding user response：

First create the string for the value and percent sign.

Then use that string with the formatting.

You can do the first part using a string output stream. And you can combine it into a single statement:

std::cout << std::setw(13)
          << (std::ostringstream{ } << std::noshowpoint << value << '%').str()
          << "|\n";
