Answer 1

Input a string instead. Use a for each loop to do the conversion, or whatever the loop contents are.

std::string v;
std::cin >> v;

for (char i : v) {
// your stuff.
}

// or

for (int i = 0; i < v.length(); i++) {
// your stuff.
}

C++ STL ( <algorithm> ) also has std::transform and ::tolower, which you can use to convert a string to lowercase, if you don't want to manually do the conversion.

std::transform(v.begin(), v.end(), v.begin(), ::tolower);
