c++ output statement

The C standard library provides a rich set of input/output functions. C's I/O occurs in streams, which are sequences of bytes. If a stream of bytes flows from memory to a device (such as a display, printer, disk drive, network connection, etc.), this is called an output operation.

Standard output stream (cout)

The predefined object cout is an instance of the iostream class. The cout object "connects" to the standard output device, usually the display screen. cout is used in conjunction with the stream insertion operator

#include <iostream>
 using namespace std; 
int main( ){
   char str[] = "Hello C++"; 
   cout << "Value of str is : " << str << endl;}

When the above code is compiled and executed, it produces the following results:

Value of str is : Hello C++

C Depending on the data type of the variable to be output, the compiler selects the appropriate stream insertion operator to display the value. The
