Remove/Insert Characters

[WGP]

Two questions...

1. How do I find and remove a character in a string?
For example with "1,200,000" I need to strip off the commas.

2. How would I insert a character?
For example with "18000" I need to insert a dot before last 2 digits (180.00).
Last 2 digits will not always be zeros.

I'll let the code speak for itself

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

int main()
{
  int i, j, n;
  char str1[] = "1.200.00,313";
  char *str2;
#ifdef ONE
  /* make enough room to copy the number */
  str2 = (char*)malloc(strlen(str1)*sizeof(char));
  for(i=0,j=0;str1[i];++i)
    {
      if(str1[i] == '.' || str1[i] == ',')
	continue;/* skip it */
      str2[j++] = str1[i];
    }
#elif TWO
  /* make enough room for the comma */
  str2 = (char*)malloc((strlen(str1)+1)*sizeof(char));
  /* backwards copying */
  for(i=strlen(str1),j=strlen(str1)+1,n=0; i>=0; --i,--j, n++)
    {
      str2[j] = str1[i];
      if(n==2)
	str2[--j] = '.';
    }
#else
  printf("Please compile with ONE or TWO defined\n");
  printf("ie: gcc -DONE\n");
  return 1;
#endif
  str2[j] = '\0';
  printf("str1: %s\n", str1);
  printf("str2: %s\n", str2);
  free(str2);
  return 0;
}
