itoa() Convert Integer to String
#include <stdlib.h>
char *itoa(value,string,radix);
int value; Number to be converted
char *string; String result
int radix; Base of value
itoa() converts the integer 'value' to a null-terminated string and
stores it in 'string'. 'radix' specifies the base to be used in
converting 'value'; it must be in the range 2 - 36. If 'value' is
negative and 'radix' is 10, the first character of 'string' is a
minus sign (-).
Returns: A pointer to 'string'. There is no error return.
Notes: Enough space for 'string' must be allocated to hold the
returned string. itoa() can return up to 17 bytes.
-------------------------------- Example ---------------------------------
The following statements convert an integer to a string and print it
out.
#include <stdlib.h>
#include <stdio.h> /* for printf */
int radix = 10;
char buffer[20];
char *strptr;
main()
{
strptr = itoa(100,buffer,radix);
printf("The amount converted: %s\n",strptr);
}
