Hi
I need four simple functions:

1 - Convert Hexadecimal to Decimal
2-  Convert Octal to Decimal
3-  Convert Decimal to Hexadecimal
I can use the format specifiers in printf but I prefer to have a function that returns a valuer into a variable
4-  Convert Decimal to Octal
I can use the format specifiers in printf but I prefer to have a function that returns a valuer into a variable

Thanks

Why don't you use the format specifiers to sprintf(), then return the modified value in a function?

No that difficult with strtol(), which has the base as third parameter.
As an example Decimal to Hex (no error checking).

3.
char *dec2hex(char *in)
{
  char *out = malloc(100);
  char *tmp;

  sprintf(out, "%lx", strtol(in, &tmp, 10));

  return out;
}
