c++ - Ascii name of value

Question

Is there a way to get the name of the value of ascii.

for example

0x08 or just 8 is the backspace

can I get the name "Backspace" in c or c++?

In short, no. Easily worked around, though.

If your ASCII code is < 32, here's table of standard ASCII control character abbreviations you can use:

char *ascii_cc[] = {
  "NUL", "SOH", "STX", "ETX", "EOT", "ENQ", "ACK", "BEL", 
  "BS",  "HT",  "LF",  "VT",  "FF",  "CR",  "SO",  "SI",
  "DLE", "DC1", "DC2", "DC3", "DC4", "NAK", "SYN", "ETB",
  "CAN", "EM",  "SUB", "ESC", "FS",  "GS",  "RS",  "US" };

Then just index into that array of strings by the value of the char you're interested in. e.g.

char c = 8; /* backspace */
printf("ASCII control code = %s
", ascii_cc[c]);
