The first ASCII value is 0, called NUL (null character). ASCII values 0–31 are control characters, and 32 is the space character.

Quick Scoop

  • 0 = NUL.
  • 32 is not the first value; it is the first printable ASCII character, which is a space.

In plain terms

If you meant the first value in the ASCII table, it’s 0. If you meant the first visible character in ASCII, it’s 32, the space character.
