Why is the use of the "using namespace std;" directive common in C++ programs?

  • It allows access to standard C++ libraries
  • It eliminates the need for including header files
  • It improves program performance
  • It reduces code complexity
"using namespace std;" is used in C++ programs to simplify the use of standard C++ libraries. It eliminates the need for prefixing standard library elements with "std::" and thus reduces code verbosity and complexity. It doesn't affect program performance or eliminate the need for including header files.
