C++ examples for STL:string
Check for anagrams.
#include <iostream> #include <cctype> #include <string> using std::string; int main() {/*from w w w . j a v a 2s . c om*/ string word1 {"level"}; string word2 {"level"}; if (word1.length() != word2.length()) { std::cout << word1 << " and " << word2 << " are different lengths so they can't be anagrams!" << std::endl; return 0; } string word2_copy {word2}; // Copy word2 - because we will delete characters for (int i {}; i < word1.length(); ++i){ // Loop over all the characters in word2 for (int j {}; j < word2_copy.length(); j++) if (std::tolower(word2_copy[j]) == std::tolower(word1[i])) { word2_copy.erase(j, 1); // Character found so erase from word2 break; } } std::cout << word1 << " and " << word2 << " are " << (word2_copy.length() ? "not" : "") << " anagrams of one another." << std::endl; }
