Caps Lock Strings

[firstlast]

Is there anyway you can switch the caps lock to fix the text in the string? I've came up with something here, but are there any hints that could help me out?

#include<iostream> 
#include<string> 
using namespace std; 
int main( ) 
{ 
	string s ("cAPS lOCK iS cURRENTLY oN!");
	 
	while (s.find("upper-case") != string::npos)
		s.replace(s.find("upper-case"), 3, "lower-case");
	while (s.find("lower-case") != string::npos)
		s.replace(s.find("lower-case"), 3, "upper-case");

	cout << s << endl;
		
	return 0;
}

There is no function to find and change an entire string to upper or lower case. But there is a function to test and change individual characters.

#include <cctype> 

if (isupper( c ))
{
	c = tolower( c );
}

if (islower( c )) 
{
	c = toupper( c );
}

In this code, c is the character you are changing (so it will be a reference to an element in your string, like s[3] or s[n].

Take care to notice that once you change a character's case that you not change it back with the next if statement.

You can't find "upper-case" in your string, since it does not have the text "upper-case" in it:

    "This is not upper-case."    (found at index 12)

    "I yam what I yam."          (not found)

Hope this helps.

There is also this way..

string s ("cAPS lOCK iS cURRENTLY oN!");
	 
	int len = s.length();
	for(int x = 0;x < len; x++)
	{
		if (s[x] >= 97 && s[x] <=122)
			s[x] = toupper(s[x]);
		else
		if (s[x] >= 65 && s[x] <=90)
			s[x] = tolower(s[x]);
	}
cout << s << endl;

Use' toupper' and 'tolower' in the <ctype.h> header file.

LOL, another complete solution. Why bother using toupper() and tolower() if you aren't going to use isupper() and islower() also?

I'm not going to give someone the complete answer.
