In this case there is usually used standard container std::map<std::string, size_t><\/code><\/p>\n

For example<\/p>\n

#include <iostream>\n#include <string>\n#include <map>\n\nint main()\n{\n   std::map<std::string, size_t> m;\n   std::string word;\n\n   while ( std::cin >> word ) ++m[word];\n\n   for ( const auto &p : m ) std::cout << p.first << '\\t' << p.second << std::endl;\n}\n<\/code><\/pre>\n
You should press either Ctrl + Z (in Windows) or Ctrl + D (in Unix) that to finish the input of words.<\/p>\n
Or you could use function std::getline<\/code> instead of operator >><\/code><\/p>\n
For example<\/p>\n
#include <iostream>\n#include <string>\n#include <map>\n\nint main()\n{\n   std::map<std::string, size_t> m;\n   std::string word;\n\n   while ( std::getline( std::cin, word ) && !word.empty() ) ++m[word];\n\n   for ( const auto &p : m ) std::cout << p.first << '\\t' << p.second << std::endl;\n}\n<\/code><\/pre>\n
In this case that to finish the input you need to enter an empty string that is to press simply ENTER key.<\/p>\n
If the input is<\/p>\n
Spain\nEngland\nEngland\nFrance\n<\/code><\/pre>\n
The output will be<\/p>\n
England 2\nFrance  1\nSpain   1\n<\/code><\/pre>\n<\/p><\/div>\n
