# Simplest way to convert integer to char

Posts: 31Member
Integer to char, the [b]simplest[/b][u][/u] 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.

You gotta use the [b]str[/b] 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:[code][color=Blue]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.[/color][/code]

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