The easiest way to append is to use sprintf function, which is quite similar
to printf, except that it prints into the specified buffer:

const char* text = "this is my text";
int num = MyconvertFunction(text);

char temp[11]; // Should be enough for 32 bit signed int. ( 9 positions +
sign + trailing zero )
sprintf(temp,"%d",num);

If you allocate enough memory to contain your original text and the string
representation of the number, you can do:

char temp[100]; // my string will never be longer
sprintf(temp,"%s%d",text,num);

I'm not sure I understand your second question.

Yakov.
