Simplest way to convert integer to char Posted by blackr1234 on 5 Feb 2011 at 5:42 AM
Integer to char, the simplest way.

Like the str function: str(integer VAR, string VAR).
But I need integer VAR --> char VAR.

Example:
1 to '1'
123 to '123'
Also, -1 to '-1' if possible.

Anyone any idea, please?

You gotta use the str procedure and process the resulting string, easy, since every string is an array of chars. Even if would be possible, you couldn't convert 123 or -1, only single digit positive integers. Here's a simple method:
var i,j:integer;
    s:string;
    ch:array[0..255] of char absolute s;
       { "ch" occupies the same place in memory as "s"}


begin
 repeat
  write('Enter a value (0 to quit): ');readln(i);
  str(i,s);
  for j:=1 to byte(ch[0]) do  { ch[0] is the length marker }
   writeln('ch[',j,']=',ch[j]);writeln;
 until i=0;
end.

Thanks for reply, Atex.

Question: As you have said only a single digit is possible, then how about chr(integer+48)?

Please check your mailbox, I have mailed you a letter 2 days ago.

Thanks v. much,

chr converts a value to a char type, it accepts a byte, so doesn't matter what you pass down to it, will only convert the lower 8bit of the argument.

str does the same thing but returns a string type, so for only 1 digit arguments returns a 1 length string which is a char ( although is stored as 2 bytes not 1 like a char).
