problem with pointer to char

[pari]

i have a program where user enter a float val(123.45) & this is stored as string. i use strtok to break it into 2 parts. period is the delimiter. now i have to print the value in words that is One hundred and twenty three.

my question is as strtok returns char * how to traverse through each character(1 then 2 then 3) or how to copy value returned by strtok in a array & then traverse through it? any help will be apreciated greatly!! is there any alternative to this.

i tried converting into int but then how to traverse is the problem.

Show us the code you have from the problem.

ok...... here it is....if i can figure out how to go thru each character then i can complete this prog. thanks for looking!

#include <stdio.h>
#include <string.h>


#define MAX    30	
#define SIZE   10

#define SPERIOD	"."
#define DECIMAL	".00"
#define SPACE	" "

#define PERIOD    '.'
#define ZERO        '0'

#define ONE	'1'
#define TWO	'2'
#define THREE	'3'
#define FOUR	'4'
#define FIVE	'5'
#define SIX	'6'
#define SEVEN	'7'
#define EIGHT	'8'
#define NINE	'9'

others you can think yourself;

Could do something like this

char    IntWordArray[10][64] ={"zero","one",........,"ten"};
char    sBuffer[128]='\0';
double  fInput=0,fTemp=0;
int         =0, iTenIndex=0, iUnitIndex=0;

iHundredIndex = fInput/100;
if(iHundredIndex>10)
     return FALSE
else
{
       fTemp=fInput-(iHundredIndex*100);
       iTenIndex=fTemp/10;
       if(iTenIndex>10)
               return FALSE
       else....................
}
//get user input as fInput
sprintf(sBuffer,"Number %g is %s hundreds, %s tens and %s units." , 
           fInput , IntWordArray[iHundredIndex] , IntWordArray[iTenIndex] , IntWordArray[iUnitIndex]);
