Hi,
How can you make your console write letters?
For exemple, A, B, C and so on,
So I can write any kind of words.

Of course! For example:

Code

char text[] = "Hello world!";
int main() {
__asm__("mov $text, %edi");
__asm__("call puts");
}

thanks but I've been heard wrong...

Is there a way to convert numbers to Letters? Like number 65 = A
So, Let's say I want my console to drop me something like
A
B
C
D
E
... I could write something like

int Number = 65
printf ("%(whatevergoeshere)", Number)

And it would appear in the console as A

Code

int num = 65
while(num > (char)'A' && num < (char)'Z')
{
printf("%c", (char)num);
num++;
}

You're not doing anything here but to convert a number to a char. It would print "65" as being string, thats all

Codeint num = 65
while(num > (char)'A' && num < (char)'Z')
{
printf("%c", (char)num);
num++;
}

cant believe i was this tired when i wrote that. and even more surprised no one called me on it lol

Code

int num = 65
while(num > (int)'A' && num < (int)'Z')
{
printf("%c", (char)num);
num++;
}

^fixed

edit:: could so go

int num = (int)'A';

if you really wanted to confuse someone lol.

Why would anyone call you on that? Both versions of your code do exactly the same thing (and use < and > operators where you wanted <= and >= respectively).
