Question

[crptcblade]

Works for me

[filburt1]

1. First tell us the error
2. Try including <ctype.h>

I want to transform I into lowercase
as if I is an CIN from the user.

Please give advice

I'm not really following. You cin a char into I, say 'V', and tolower() makes it lower case. It works for me.

[prog_tom]

Can you post the code of getting lowercase of a CIN? Thanks

[crptcblade]

#include <iostream>

#include <time.h>
#include <math.h>
using namespace std;
char I;

void main()
{
	system("cls");


	cin >> I;
	I = tolower(I);
	cout << "\n\tWelcome to this hot stuff! " << I << endl;

	system("pause");
	
	exit(0);
}

your code works for me.

But only 1 letter...

[prog_tom]

I want it to do it for up to 256 chars

It will work for all the upper case letters. I think, I is confusing you. Use this code:

#include <iostream>
 
#include <time.h>
#include <math.h>
using namespace std;
char word;
 
void main()
{
    system("cls");
 
 
    cin >> word;
    word = tolower(word);
    cout << "\n\tWelcome to this hot stuff! " << word << endl;
 
    system("pause");
    
    exit(0);
}

Now, if you type "A", it`s gonna print ``a``. Samething for all the other letters.

If you want to uppercase a whole C style string you can iterate trough the array and lowercase each letter

char I[256],*i;
cin >> I;
for(i=I;*i;*i++=tolower(*i));

[[praetorian]]

that's pretty it the easiest solution..........just use the for loop or any other iteration command

[CornedBee]

keda, this is the most confusing code I've EVER EVER seen! Such things easily fall to the postfix/prefix trap! I don't fear that you'll ever fall into it, but it can easily hit others in snippets like this...

I know the operator presedence pretty well
