Bades,I want to parse through the string .The below code is compliing but i am not getting the desired output.
[code
main()
{
string str;
cin>>str;
int size=str.size();
for (int i=0; i<=size ;i++ )
{
cout<<str[i];
}
}]
can u please tell what is worng here..
what output are you expecting? Since you did not put a space between characters they will all be scrunched up together so that it looks like out output the string instead of individual characters. try this
Code:cout<<str[i] << " ";
Specify what the undesired result is.
If it cuts off at spaces, use cin.getline();
Can't say for sure since you don't note what kind of error you're getting, but I'd guess you're entering a space in the input intended for str. cin only grabs from the input stream until the next whitespace, so if you enter:
why is this not working
to the program, str will only be assigned "why".
Also, make sure you're using code tags properly. That's what the edit button is for.

Will end up looking like this:
(Thanks quzah)Code:enter your code here

There is a difference between tedious and difficult.
The only thing that is "wrong" with your code is that you access a character passed the string's bounds. Using [] with an index greater than or equal to size() is undefined.
You should use i < size instead of i <= size.
Just to explain a little further what Daved is saying. If you have an string of length 3,
string str = "yes";
you can treat it as an array. But, arrays start at index position 0. So, the 'y' is at index position 0, the 'e' is at index position 1, and the 's' is at index position 2. Note that index position 3 doesn't exist. The general rule is that index values go up to one less than the size of the array.
You also might want to consider proofreading. Is it possible you didn't notice that your code tags failed to work?
