string to integer
============

int nVal = atoi(szSTR);


integer to string
============

char szSTR[10];
itoa(nVal, szSTR, 10);

int strtoint(char* pch)
{
       return itoa(pch);
}


char* inttostr(int no, char* pch)
{
      return itoa(no, pch, 10);
}

Is that what you want...?

try this if you need only one parameter passed to the functions

//----------------- include ---------------------------------------

#include <stdlib.h>

//----------------- declarations ---------------------------------

int strtoint(char* pch);
char* inttostr(int no); //only the int parameter

//----------------- definitions -----------------------------------

int strtoint(char* pch)
{
       return atoi(pch);   // atoi function, not itoa!!
}


char* inttostr(int no) // only the int parameter
{
      char pch[10] = "";
      return itoa(no, pch, 10);
}

Why is this in the "time tested" solutions?  For most systems out there, it is technically incorrect:

1: a 32-bit "int" value, when converted to a string can occupy 10 character places; so a buffer of only 10 chars is incorrect: there is no room allocated for the terminating NUL (not NULL) character.

2: The accepted answer basically returns the address of a non-static local variable, which is incorrect.  It might seem to work, but that does not mean it is correct.

Peace!
