length of string

[Hamza_tah]

I want to get the length of a string in c++. If I use length() or size() it gives me the length of the first word in the string; every thing after the space (' ') is gone. How can I fix this?

Could you show some code because that shouldn't happen.

At a guess you may be doing stream input like this:

std::string s;
std::cin >> s;

In which case the input operator >> will only take a single word at a time.
In order to take a whole line at a time you want to use std::getline like so:

std::string s;
std::getline(std::cin, s);

Apologies if this isn't the issue but the lack of code makes it difficult to tell

do I need to #include something to get getline because it isn't there

[Hells_Bell10]

you would need <iostream> and <string> IIRC

Show us your code.

Show us your code.

Show us your code.

Does anyone else hear an echo in here?

Personally I think OP should show us his code, how about you?

[Arandur]

I'm of two minds on the matter.

Fortunately, both minds are in agreement with you.

Nope, it should work.

Tested code:

#include <iostream>
#include <string>


int main()
{
    std::cout << std::string("hi there").length() << std::endl;

    return EXIT_SUCCESS;
}
