Hi,
it's me again with one question from my last program.
Can I go through the string backwards by using if(ret != -1) ?
Like this:

int stringToPositiveInt(char s[ ]) {
int checkString(string a);
int ret = checkString(a);
if(ret != -1) {
return s[atoi(a)];
}else{
return -1;
}
}

thank you,
albina

>return s[atoi(a)];
Since your function returns an integer, this should be:
return atoi(a);

And can you explain your question?
