Case sensitive?

[967L1hU5]

I'm making a program where there is a lot of commands. To get a command from the user, I use:

string x;
getline (cin, x);

And that works fine and all, but I don't like that if the user types, say "action", that it would have a different effect than if the user typed "Action", or "aCtIoN". So my question is, is there a way to sort of convert strings to all caps, or no caps, so I would only have to program the one string, or any other way?

You can use std::transform():

#include <string>
#include <algorithm>
#include <cctype>

std::string s = "SoMetHinG LiKe tHis";

std::transform(s.begin(), s.end(), s.begin(), std::ptr_fun<int, int>(tolower));

You can use the string library.

ToLower() Returns a copy of this string converted to lowercase.

ToUpper() Returns a copy of this string converted to uppercase.

Or you can use:

#include <iostream>
#include <cctype>
#include <string>

void Lower(std::string str&)
{
  
     for (int i = 0;  i < str.size(); i++)
    {
           str[i] = tolower(str[i]);
    }
}

int main ()
{
    std::string str = "SoMeThINg";
    Lowr(str);
    cout << str;
    return o
}

This will output:
