Thread: Character to Ascii

Hello there, I'm stuck trying to convert any scanned character to ascii. I know that printf("%d", a); will print the value of the letter a (that is 74 or 75), but i can't get to save it.

This is where I'm at

Code:

int x;
char letter;
print("enter a letter\n");
scanf("&c", letter);
x = (int)letter;

but that doesn't seem to work.

any input is highly appreciated,

thanks.!

are you sure the ASCII value of a is 74 or 75? this code prints 97.

Code:

char letter;
printf("enter a letter\n");
scanf("%c", &letter);
printf("%d", letter);

He may be talking hex, but I think that's in and around the 60's ...

I believe a is 0x61 in hex.

The character has an integer value.

Code:

#include <stdio.h>

int main(void)
{
   char letter = 'a';
   printf("letter = '%c' (using %%c)\n", letter);
   printf("letter = %d (using %%d)\n",  letter);
   printf("letter = %#x (using %%x)\n", letter);
   return 0;
}

/* my output
letter = 'a' (using %c)
letter = 97 (using %d)
letter = 0x61 (using %x)
*/
