this article is related with my previous topic , which was about c++ programming , here i m going to discuss that article more.
C++ programming
Std::cout
Standard output stream object
“Connected” to the screen
std:: specifies the "namespace" which cout belongs to
std:: can be removed by the use of using statements
with the help of using statement we can write cout instead of std::cout as we would observe in the next program.
<<
Stream insertion operator
Value to the right of the operator (right operand) inserted into output stream (which is connected to the screen)
std::cout << “Welcome to C++!\n”;

Testing and debugging
Bug
A mistake in a program
Debugging
Eliminating mistakes in programs
Term used when a moth caused a failed relay on the Harvard Mark 1 computer. Grace Hopper and other programmers taped the moth in logbook stating: “First actual case of a bug being found.”
Program errors
Syntax errors
Violation of the grammar rules of the language
Discovered by the compiler
Error messages may not always show correct location of errors
Run-time errors
Error conditions detected by the computer at run-time
Logic errors
Errors in the program’s algorithm
Most difficult to diagnose
Computer does not recognize an error
