Removing spaces from strings

I'm reading in very large numbers that may have unusual spacing... like 123 45 43657 4 And I need to store this number in an array of ints without all the spaces :) I'm really not very familiar with string manipulation so anything will help!!!

Code:

---

#include <stdio.h>

int main() {
    int numbers[255];
          int x = 0;
    int numbers2[255];
          int y= 0;

    while(numbers[x] != '\0') {
          if(numbers[x] != ' ') {
                  numbers2[y] = numbers[x];

                  ++y;
          }

          ++x;
    }
   
    return 0;
}

look good?

:) It looks exactly like what I was trying to do... just so much cleaner! I'll try it out... Thanks!!!

Read the input into a string (char array), then loop through each character, testing it with isdigit(), and then storing the number in the int array.


>>while(numbers[x] != '\0') {
Here, numbers[x] is unitialised. Also, if the data is in an int array, the its already number, so checking against ' ' is like checking against 32 (assuming ASCII).

Maybe something in here will help you.

Hammer, going by the way you suggested would that method index a number more than one digit or would it only index a one digit number? Would it treat 106 as 106 or as 1, 0, 6?

ADD::

until a chararacter is NOT a digit then increment the array index

if you know they are going to be a space then use

isspace()

Code:

---

int        CheckStringForPunctuation(HWND hWnd,char *sBuffer)
{
        char                                sTempBuffer[L_STRING], sNewString[L_STRING], *pNew=NULL,  *pOld=NULL;
        int                                        iLen=0;

        iLen=lstrlen(sBuffer);
        if(iLen>=L_STRING)
                return FALSE;//not enough space
       
        sprintf(sTempBuffer,"%s",sBuffer);
        pOld=sTempBuffer;
        pNew=sNewString;

        while(*pOld != '\0')
        {
                while(ispunct(*pOld))        *pOld++;
                while(isspace(*pOld))        *pOld++;
                *pNew++=*pOld++;
        }
        *pNew='\0';
        sprintf(sBuffer,"%s",sNewString);
        return TRUE;
}

ANS: 1, 0, 6.
Maybe that is the requirement, at least thats how I read it. But as usual, its open to interpretation.
