Hi,
This should do it.

char ch = 'A';
printf("%d",ch); Pappy
You learn something everyday.

Or you could put it in a loop to print ou a charcter set.

#include<stdio.h>

void main()
{
int count;
for(count = 0;count<127;count++)
printf(&quot;%d = %c &quot;,count,count);
}

In C/C++, characters are stored internally as binary. On ASCII system, they are stored as ASCII value. Thus, you can do:

    char ch = 'A';

or

    char ch = 65;

or

    char ch = 0x41;

They are all equivalent.

Therefore, taking any value, say 65. You can treat it like any integer value, or ASCII representation of character ¡¥A¡¦. Internally, the program always uses numeric 65. The only time you need to differentiate 65 or 0x41 or ¡¥A¡¦ is when you output the value in some human readable context. In this case, you can use the printf() format specification to ¡¥translate¡¦ how the data needs to be presented.

To output decimal 65:

    printf("%d", ch);
[\code]

To output hex 0x41:
[code]
    printf("0x%X", ch);
[\code]

To output character ¡¥A¡¦:
[code]
    printf("'%c'", ch);
[\code]

Hope this answer your question.

here is a hellp full coding for ascii codes.
just press the the key for which you want to see the ascii code. press enter to terminate the program.

void main(void)
{
char ch;
while((ch=getch)!='\r')
{
printf(&quot;%c=%d&quot;,ch,ch);
}
}
