Subject: RE: Picture Specifications for UNIX
I am not sure what does it mean by Picture Specifications.
But the easiest way to write your own itoa function.
so while calling printf function, insert your own itoa
function.
NOTE: I am writing the code as I think without any compilation, this
is just to demonstrate how one can invent one's printf pattern.
-------------------------------------------------------
char *itoa(int, char *,int);
printf("Number = %d, Pretty number = %s \n",
NUMBER_TO_PRINTED,itoa(NUMBER_TO_PRINTED, buffer, PRETTY_NUMBER));
where itoa() is :
char *itoa(int number, char *buffer, int mode)
{
static char *ch;
int pp;
/******* Make sure buffer is large enough to hold the output format *******/
ch = buffer;
switch (mode) {
case PRETTY_NUMBER:
pp = 0;
do {
pp++;
*ch++ = number % 10 + '0'; /* works for ASCII */
if ( (pp % 3) == 0) *ch++ = ',';/* Add comma */
} while ( ( number /= 10) );
if (number < 0) *ch++ = '-';
*ch = '\0';
/* The number will come out reverse, and there will be one extra
comma if the number is a multiple of 3 digits. But you get the idea,
the correct version is left as an exercise. I don't feel like
making my brains to work today :-)
*/
break;
case BINARY:
/* Print BINARY ! */
break;
case ETC: /* Be innovative ! */
break;
default :
*ch = '0';
*++ch = '\0';
break;
}
return buffer;
}
