Any idea why this wouldn't work?
| Code: | void Arithmetic(string number)
{
string temp = "";
for(int i = 0; i < number.length(); i++)
{
if(number[i] == '+')
{
WriteLn(temp);
temp = "";
Arithmetic(number.substr(i+1,number.length()-(i+1));
}
temp += number[i];
}
} |
This doesn't work I can't figure it out o.0 (which is odd)
Any ideas? In theory it loops through all characters and if its a + then it calls a new one, yet it messes up.

| I don't exactly see what you are trying to accomplish, there is probably an easier way than recursive function calling...

try number.length() - 1 instead of number.length()

This might work for you:
| Code: |
void Arithmetic(string number)
{
for (int i=1; i <=(int)number.length();i++)
{
if (number.substr(i, 1)=="+")
{
cout << number.substr(0, i) << endl;
Arithmetic(number.substr(i+1, number.length() - (i+1)));
return;
}
}
cout << number << endl;
}

@Kitterz Length-1 Wouldn't work It just means I am going less.
@mStorm, thanks I guess next time I should use substr through all the code
@slovach Debugging really does not help.

try Arithmetic(number.substr(i+1,number.length()-(i+2));
im not too sure about it. You make the code very confusing.
I suggest that you do it another way.

Well I got it working. Anywho I would need to make it go from another direction on list or opperations due to it saying: 1+2 = Add 1, 2.
