C++ Locale Library - operator!=

It compares locales and returns true if the locales are different or else false.

Following is the declaration for std::locale::operator!=

	
bool operator!= (const locale& x) const;

bool operator!= (const locale& x) const;

x − locale object to compare.

It returns true if the locales are different or else false.

Strong guarantee − if an exception is thrown, there are no changes in the objects.

The locale object is accessed.

In below example explains about std::locale::operator!=.

#include <iostream>
#include <locale>

int main () {
   if (std::cout.getloc() != std::locale("C"))
      std::cout << "cout is not using the locale C.\n";
   else
      std::cout << "cout is using The locale C.\n";

   return 0;
}

Let us compile and run the above program, this will produce the following result −

cout is using The locale C.
