Both lines are identical, what do you want?
Well i wanted to remove the extra spaces but,it didnt come out in the post properly
You know in html,the extra spaces are automatically removed,thats how
Lets say i have "This is a sentance"
I want "This is a sentance"
can i do it using ws manipulator or any other simple way?
TrintiyNoe,
Did you work out on this problem? If yes; then show us your code, please.
However I suggest:
string str="This is a sentance";
istringstream iss(str);
string str = "This is a sentence.";
string newStr;
int len = 0;
for(int i = 0; i < str.len; i++)
{
newStr += str[i];
if(str[i] == ' ')
while(str[++i] == ' ')
;
}
I made this in 2 mins and didn't test it. But you get the basic idea..
Actually,i encounter this in lot of probs,i use while loop to solve it,not unlike the above version,but i thought it would be easier if there is one simple way doin like a function or somethin.
Well you can always write your own function and add it to the headers and include it in all your usages. Its quite common . If its too good then it may be included in the standard headers in future ;).

;) Hope so

You can write your own function to do it. :) But doing it in a general way is not as easy as you thing. Removing all spaces is easy but leaving one space isn't because a space character could be more than just a single space. If you have "a\t\tb", is it right to replace it with "a b"? What should "a\t\t\nb" be replaced with?
Basically what i want to do is,extract the first letters of words in a string and put it in a vector.
If i have "This is the world"
I want a vector to collect only T, i, t ,w
so it would have been easier for me to just trim the string if u will and take all the chars whose previous charactor is ' '.
Did the problem now,using the old fashioned for way
but,would like that function to be added to standard library.Maybe one of u guys can do it :P
That's easy with the standard library:
istringstream iss(s);
vector<char> v;
string word;
while (iss >> word) v.push_back(word[0]);
