Question

how many variables can be used in one cout object ?
​

Answer 1

There is no upper limit for "cout" objects.

• "ostream" class contains the "cout" object.
• When the "iostream" header file gets declared, the "ostream" class gets automatically defined.
• Standard output devices like monitors can print any output using cout object in c++.
• Insertion operator (<<) is needed to insert any value in the "cout" object, which will get displayed on the screen eventually.
• The lower number of variables that can be used in a "cout" object is usually one.
• There is no upper limit to push any variable within a "cout" object
