##Using the above:

Using the above:

 std::transform(std::begin(inputString), std::end(inputString), // Source
 std::begin(inputString), // Destination (can be source) as long as it it is already large enough.
 [&loc](char c){return std::tolower(c, loc)}
 );

std::vector <char> reverseVec(std::vector<char> const& inputVec) {
 std::vector <char> reversedReturn;
 for (auto loop = std::rbegin(inputVec), loop != std::end(inputVec); ++loop) {
 reversedReturn.push_back(*loop);
 }
 return reversedReturn;
}

std::vector <char> reverseVec(std::vector<char> const& inputVec) {
 return std::vector<char>(std::rbegin(inputVec), std::end(inputVec));
}

 std::transform(std::begin(inputString), std::end(inputString), // Source
 std::begin(inputString), // Destination (can be source) as long as it it is already large enough.
 [&loc](unsigned char c){return std::tolower(c, loc)}
 );

std::vector <char> reverseVec(std::vector<char> const& inputVec) {
 std::vector <char> reversedReturn;
 for (auto loop = std::rbegin(inputVec), loop != std::rend(inputVec); ++loop) {
 reversedReturn.push_back(*loop);
 }
 return reversedReturn;
}

std::vector <char> reverseVec(std::vector<char> const& inputVec) {
 return std::vector<char>(std::rbegin(inputVec), std::rend(inputVec));
}

##Using the above:

int main()
{
 std::cout << "Enter the string you would like reversed: ";
 std::string userInput;
 std::getline(std::cin, userInput, '\n');
 auto newEnd = std::remove(std::begin(userInput), std::end(userInput), ' ');
 std::erase(newEnd, std::end(userInput));
 std::transform(std::begin(userInput), std::end(userInput),
 std::begin(userInput),
 [](unsigned char* c){std::tolower(c);});
 std::string reversedInput(std::rbegin(userInput), std::rend(userInput));
 std::cout << "Reversed: " << reversedInput << "\n"
 << "Palindrome: "
 << ((userInput == reversedInput) ? "Yes" : "No")
 << "\n";
}
