/* * * @ Javier Felipe Toribio 2018 * * challenge from sololearn user * * manipulate the text */ // Language: C++ // Task Description: Create different functions that take the original text and manipulate it according to the directions in the code. One of the functions is already implemented, and two more are available. You are free to implement new styles and conventions, too. #include #include #include #include using namespace std; string removeSpaceAndChangeNext (string str, function f) { size_t pos; for(;;) { pos=str.find(" ",0); if(pos != string::npos && pos < str.length()-1) str.replace (pos,2,f(str.at(pos+1))); else break; }; return str; } string camelCase(string str) { function nextToupper = [&] (char letter) { return string(1,toupper(letter));}; return removeSpaceAndChangeNext (str, nextToupper); } string snake_case(string str) { function underscoreAndNextToLower = [&] (char letter) { return '_'+string(1,tolower(letter));}; return removeSpaceAndChangeNext (str, underscoreAndNextToLower); } string cApItAlIzEAllvOwEls(string str) { function vowelToUpper = [&] (char c) { return ((c == 'a') || (c == 'e') || (c == 'i') || (c == 'o') || (c == 'u')) ? toupper(c) : c; }; transform(str.begin(), str.end(), str.begin(),vowelToUpper); return str; } int main() { //sample text string text = "I am coding C++ on SoloLearn"; cout << "original text : " << endl << text << endl << endl; cout << "camel case : " << endl << camelCase(text) << endl << endl; cout << "snake case : " << endl << snake_case(text) << endl << endl; cout << "capitalize vowels : " << endl << cApItAlIzEAllvOwEls(text) << endl; return 0; } /* OLD CODE // // Created by SoloLearn string camelCase(string str) { // Implement the camelCase return str; } string snake_case(string str) { // Implement the snake_case return str; } string cApItAlIzEAllvOwEls(string str) { for (unsigned i = 0; i < str.length(); i++) { if (isalpha(str.at(i))) { char vowel = str.at(i); switch (vowel) { case 'a': case 'e': case 'i': case 'o': case 'u': str[i] = toupper(str.at(i)); break; } } } return str; } int main() { //sample text string text = "I am coding C++ on SoloLearn"; //cout << camelCase(text,f) << endl; //cout << snake_case(text) << endl; cout << cApItAlIzEAllvOwEls(text) << endl; return 0; } */
