C++ strtok

[eboyjr14]

Let's say that:

argv[i] = "Db4+2";

How can I get the number 2 from that as an integer?

In PHP it would be easy:

[PHP]
<?php
$argv[$i] = "Db4+2";

$argvarr = explode("+", $argv[$i]);
echo $argvarr[1];
// Would return: 2

?>
[/PHP]

I know PHP fluently, and I am just learning C++.

Remeber there may not be a +2 or whatever, it could just be Db4

Maybe something like:

int length = strlen(argv[i]);
int value = 0;
for (int ctr = 0; ctr < length; ++ctr)
{
   if (argv[i][ctr] == '2')
   {
       value = argv[i][ctr] - 48;
    }
}
cout << value << endl;
 

This is just a loop that searchs for the character 2 and if found changes it to an integer 2 by subtracting the offset from '2' to 2 in the ASCII table.

but... it could be any number, not 2. But... I already figured it out. I would show you the source but its on my iPod and I don't have it with me. Thx, anyway!

I presume you know how to use the ASCII table. Yes?
