This method does the transform in-place. Alternate

methods might return a new copy or use a stream manipulator.

/// \brief in-place convert string to upper case

/// \return ref to transformed string

void str_toupper(std::string &str) {

std::transform(str.begin(),

str.end(),

str.begin(),

std::toupper);

}

/// \brief in-place convert string to lower case

/// \return ref to transformed string

void str_tolower(std::string &str) {

std::transform(str.begin(),

str.end(),

str.begin(),

std::tolower);

}

here is sample usage code:

#include <iostream>

using namespace std;

int main() {

string foo("_upperCas3Me!!");

str_toupper(foo);

cout << foo << endl;

str_tolower(foo);

cout << foo << endl;

return 0;

}

string array = "alphaBETA";

System.Console.WriteLine(array.ToUpper());

System.Console.WriteLine(array.ToLower());
